I grabbed this one after a run of heavy books and wanting something fast that still had teeth. A friend told me it starts like Rear Window at a lake house and ends somewhere completely different, and that was enough. Published in 2022 by Dutton, it follows a washed up actress who drinks too much and watches too much, until the watching turns into a missing person case that pulls her own marriage back into view. This is a full retelling, so every big turn is below, including the one people argue about.

Drinking alone at Lake Greene

Casey Fletcher is the kind of narrator you want to shake and also sit with a little longer. She was a working actress in New York, stage and some screen work, married to a screenwriter. Then her husband died in Lake Greene the summer before, drowned in the same water she can see from her porch, and her life slid sideways. She showed up drunk to a Broadway performance and got fired for it. The press had a field day. Her family has an old cabin on Lake Greene in Vermont, small and a bit ragged, and she hides out there because there is nowhere else that feels quiet.

Her days have a shape that is sad to admit is familiar. Bourbon in the morning coffee. Bourbon in the afternoon straight. Her late husband's old binoculars from birding, heavy in her hands, lifted to look across the water. Sleep that comes in pieces. She tells herself she is resting. She is really waiting for the noise in her head to stop.

Then there is the view. Directly across the lake sits a modern glass and steel house, all sharp angles and lit rooms at night, the kind of place that looks staged even when people are just making dinner. That is where Tom lives with his wife Katherine. Tom is a tech guy, an app developer trying to keep a startup alive, the sort of man who talks about scale and runway and gets tense when the wifi lags. Katherine was a runway model, still striking in the way that makes strangers stare at grocery stores, now mostly out of the spotlight and living upstate part time. Casey watches them the way you watch a show you do not want to admit you follow. Who is cooking. Who is arguing. Who swims, and when.

Sager splits the timeline into Now, Before, and Later, and it works better than it sounds. In the Now, Casey is being questioned by a detective who asks if she is still spying on the Royces, and upstairs in Casey's own house someone is tied to a bed with a towel in their mouth while Casey says, tell me what you did to Katherine. You do not know who is tied up or why. Then the book jumps back to Before and earns that weird opening one slow afternoon at a time. It is a clever hook because you keep reading to find out how a lonely drunk with binoculars ends up holding someone prisoner.

What I liked here, early on, is how specific the drinking feels. Casey counts pours and lies about them. She hides bottles. She wakes up on the porch with a crick in her neck and no memory of falling asleep. She tells herself she will cut back tomorrow. It never feels glamorous. It feels like grief with a hangover on top, and it makes her an uneasy guide. You believe she saw something. You also do not fully trust her about what it was.

The rescue and the wine

The day everything shifts starts ordinary. Casey sees what looks like a body floating out in the middle of the lake. For a second she thinks it is Len again, the memory sitting right on top of the present. She takes her motorboat out through chop, heart hammering, and finds Katherine face down and barely responsive in the water.

She hauls her in, gets a life vest on her, and Katherine comes back coughing and crying. It is messy and frightening and real. Tom races over after, full of thanks that sound sincere but clipped, like a man who is already calculating how this looks. That night Tom and Katherine bring Casey an expensive bottle of wine to say thank you. With them is Eli Williams, a novelist neighbor who lives nearby and likes to hold court. Eli tells a story about the lake that lodges in your head. He says you should not swim in the day when you can see your reflection, because the lake can take your soul and let it jump into someone else. Everyone laughs a little. Casey files it away as local color. It does not feel like foreshadowing yet. Later you wish you had underlined it.

The wine night matters for small details. Katherine drinks hard and then fades fast, complaining of headaches and strange blank spots where time seems to skip. She collapses, and Tom gets sharp with her, calling her an embarrassment as he gets her home. It is ugly in a way that feels married, not performed. Katherine texts Casey the next morning to apologize, warm and funny, and Casey realizes with a chill that she never gave Katherine her phone number. How did she get it. Tom. A friend of a friend. A guess. It nags at her.

From there the friendship grows in fits. Katherine comes over for coffee. She talks about fame and how it warps everything, about money keeping Tom's company afloat, about Tom's startup burning cash and her own funds filling the gap. She jokes at one point that Tom would kill her before letting her leave, and laughs, and Casey laughs too, and neither of them fully means it as a joke. Casey keeps watching through the binoculars. She sees Tom watching Katherine too, from inside that glass house. She sees a fight where Katherine actually punches Tom in the jaw. She sees Katherine standing at a window at night staring at her own reflection a beat too long, like Eli's story got under her skin as well.

Then comes the morning with the scream. Casey wakes on the porch, mouth dry, head pounding, with the sound of a woman screaming still hanging over the water. She calls Katherine. No answer. She boats over. Tom is alone on the dock, calm in a way that reads wrong. He says Katherine went back to New York that morning. Just like that. Gone.

Everyone looks guilty from across the water

This middle stretch is pure peeping thriller, and I mean that as praise. Casey does what you would do if you drank too much and had too much time. She checks Katherine's social media and finds posts saying she is in Manhattan, smiling in photos. But the details do not line up. Casey asks her cousin in the city to check Katherine's building. The doorman says Katherine has not been there. She is still supposed to be at the lake. So who posted those photos, and when were they taken.

Casey leans on Boone Conrad, the guy staying next door. Boone is a handyman, easy to talk to, sober, widowed himself, with a steady manner that makes Casey feel both safer and more reckless. He says he heard a scream that same morning too and thought it was Katherine. That small confirmation steadies her. Maybe she is not imagining this. Boone used to be a cop, so he calls a former colleague, Wilma Anson, now a detective, to ask quietly what to do.

Wilma is great. Dry, tired, professional, not interested in lake gossip. She tells them to stop playing detective. Then Casey finds a broken piece of the wineglass Katherine drank from on the night she vanished, and Wilma's tone changes. Lab talk starts. Wilma lets slip that police have been looking hard at Tom in connection with something larger. Three young girls from the surrounding area disappeared and are presumed dead. There is talk of a serial killer. Suddenly the missing wife across the lake might sit next to something much darker.

Casey keeps snooping anyway. She watches Tom carry tarps and rope and an axe around his property, which looks terrible through binoculars and might be innocent up close. Yard work looks like murder prep when you want it to. She finds Katherine's phone hidden in a dresser drawer in the Royce house, full of missed calls. She and Boone start mapping the missing girls cases, dates and places, trying to see a shape.

Then Sager tilts the floor. Casey learns Boone was once a suspect in his own wife's death. People cleared him, sort of, but the fact hangs there. And those missed calls on Katherine's hidden phone. Many of them are from Boone. Why was Boone calling Katherine over and over. Boone has answers for all of it, reasonable ones, but Casey is drunk and grieving and scared, and reasonable stops landing. If you have ever decided someone is lying and then read everything they do as proof, you know this feeling. The book nails that spiral. I found myself flipping suspects every chapter. Tom with money trouble and a temper. Boone with a past and too many calls. Eli with stories and bourbon and access. Even Katherine, maybe staging something. Even Casey, maybe missing something big while blacked out.

My one complaint in this section is the blackouts. They are honest to alcoholism, and Sager does not cheat with them, but there are a lot of mornings where Casey wakes up and reconstructs the night before. After the third or fourth lost evening, I started bracing instead of wondering. It still moves fast, short scenes and phone calls and boat rides, but you can feel Sager keeping cards back by keeping Casey blurry. Your mileage may vary. I was annoyed and hooked at the same time.

The basement and the name Len

Casey decides she cannot wait for Wilma or Boone or anyone. She breaks into the Royce house. The place is quiet and too tidy, glass walls showing the lake like a picture you cannot enter. She moves through rooms she has only seen through binoculars, which is a nice creepy payoff. The house she watched for weeks is suddenly around her, smelling like cleaner and lake air.

In the basement she finds Katherine. Alive. Tied up.

Tom appears. There is a confrontation, voices low and then not low, and then Katherine starts talking. Only the voice is wrong. The words, the cadence, the private details no neighbor could know. Katherine says she is Len. Leonard Bradley, Casey's dead husband.

Here is where the book swings for the fences, so let me lay it out plainly because the order matters. Len was a screenwriter, charming in the way creative men can be when they want funding or forgiveness. Casey loved him and also started to fear him. Before he drowned, she found out he had killed three girls and hidden their bodies. Young women from around the lake area, taken and kept quiet. Casey confronted him in her own way. She drugged him and drowned him in Lake Greene and told the world it was an accident. She has been carrying that since, drinking to keep the memory flat.

Len did not exactly leave. According to what Eli told as legend and what turns out to be true in the logic of this novel, the lake holds spirits and lets them move when someone sees their reflection in the water in daylight. A soul can slip from the lake into a living person. When Katherine went under and Casey pulled her out, Len moved into Katherine. The rescue that opened the book was also an invasion. The Katherine who drank wine and joked about Tom and stared at her reflection was already sharing skin with Len, or becoming him.

I know. It is a lot. On first read I sat up straight and said no aloud. Then I kept turning pages fast, which tells you something. Sager plays fair with the clues if you reread. The headaches. The blank spots. The collapse after wine. The odd text without a number. The reflection staring. The way Katherine knew things she should not know. The fainting and the personality slides that Casey read as marriage stress or drinking. All of it fits possession once you accept possession is on the table. The question is whether you wanted that table at all in a book that felt like a drunk Rear Window for two hundred pages.

Casey reacts the way I think I would, which is badly and then practically. She gets Katherine, who is Len, back to her own house. Remember the Now opening. That tied person with the towel. This is that. She demands to know what Len did with the girls. Where he put them. Len talks because Len likes to be heard, even now. Casey gets locations and sends what she learns to the authorities so the bodies can be found. It is grim and procedural in the middle of something ghostly, and that mix is strange and strong. The missing girls stop being background texture. They get names and places and weight.

Drowning on purpose

The plan Casey forms is desperate and very Casey. She cannot kill Katherine to kill Len. She will not. So she tricks Len into leaving Katherine and entering her instead. The mechanics are simple in the book's terms. Reflection, water, daylight, willingness or confusion, contact. Len wants Casey more anyway. She was his wife. She is the one who killed him. There is unfinished business there that a spiteful spirit cannot resist.

Casey then drowns herself in Lake Greene with Len inside her. She motors out, weights herself or simply lets the water take her, and goes under while holding the thought that this ends it. It is harrowing because you have watched her fear this exact water since page one. The lake that took Len, the lake she associates with guilt and press photos and bad dreams, is where she chooses to go.

She is rescued by Katherine, now herself again and conscious, who pulls Casey from the water the way Casey once pulled her. The mirror of the opening rescue lands hard. For a moment it feels clean. The girls' locations are with police. Len is supposed to be gone, washed out or trapped. Two women who were used by men in different ways sit breathing hard on a boat and understand each other without a speech.

Except Tom was never innocent in the normal human sense. This part is important and easy to miss under the supernatural noise. Tom really was trying to kill Katherine. Money, control, the startup failing, Katherine's funds as his lifeline, divorce meaning ruin. He had a plan forming, or already moving, involving drugs or staged disappearance. Casey realizes this in flashes after she comes back to herself. The ghost story was true. The domestic murder plot was also true. They were layered.

Tom comes for Casey at her house, angry that she uncovered his plot and tangled everything. He attacks her. They fight through rooms that feel small after all that open water. Casey kills him in self defense, stabbing him as he keeps coming. In the book's logic, Len's spirit is in Tom by then too, or clinging to him, which is why Tom feels both human and wrong in that fight, strong beyond sense and talking with edges of Len. Casey puts him down. When it is over, Tom is dead and Len, she hopes, is dead with him in whatever way a lake ghost can die.

The last beat is quiet. Casey and Katherine bond, not as best friends forever but as two people who survived overlapping horrors. Casey decides to stay at Lake Greene instead of selling the cabin and running back to the city. Partly to heal. Partly to watch. If Len's spirit is still in that water, she wants to be there if it tries again. The final image is not triumph. It is vigilance. Porch, binoculars, lake, but sober or trying to be, and awake.

Why the twist splits readers

Let me be direct about the part everyone fights over, because you should know before you start. The possession turn either delights you or loses you, and both reactions make sense. USA Today and BookPage praised the Hitchcock setup and the pace, and the book hit the Publishers Weekly bestseller list in July 2022. A lot of readers love that Sager commits completely. He does not wink. He treats the lake rule as real and follows it. Others, including the Daily Herald and some Goodreads reviewers in the three star range, felt the back half asks too much. A grounded story about drinking, grief, money, and a possibly murderous husband becomes a ghost story about body hopping, and no amount of planted clues fully smooths that jump if you signed up for realism.

I land somewhere in the middle. I bought the emotions even when I wobbled on the mechanics. Casey's guilt over killing Len, and what that does to her drinking and watching, feels true. Tom wanting Katherine dead for money while a dead man wears Katherine's face is almost too much plot, but Sager keeps scenes short and physical, boats and basements and phones, so it never gets sleepy. Boone and Wilma help a lot. Boone as a decent man with a bad past keeps Casey human. Wilma as a tired pro keeps the police side credible. Eli as the talkative novelist who first says the quiet lake stuff out loud keeps the legend from feeling dropped in late.

Fair criticism, though. The middle repeats beats. Another night of spying. Another morning of piecing together texts. Another bourbon bottle counted wrong. The fake Manhattan posts and the hidden phone and the tarps stretch a little thin before the basement pays them off. If you are sensitive to unlikable narrators, Casey will test you. She lies to police, drives boats drunk, breaks into houses, ties someone to a bed. Sager wants you to root for her anyway because she is trying to fix something awful she did. I did root for her, but I needed breaks from her head.

Who should pick this up. If you like fast thrillers with big swings, voyeur setups, unreliable drinkers, and endings that go strange rather than safe, you will have fun. If you need every twist to stay in the real world, this will annoy you, and the last hundred pages especially will feel like a different book. The Netflix adaptation with Paul Feig attached will be interesting to watch, because that turn is hard to film without tipping into camp. On the page, at least, it moves too fast to put down, even when you are arguing with it.

I finished it late at night and stood at my window a minute before bed, which is silly because I live nowhere near a lake. That is probably the best sign. I did not believe every step. I still felt the water.
