Meet Sean Stephens, writer and journalist. A thin, intense man. When Sean was young, his best friend was randomly killed by a serial killer. Even since, Sean has been obsessed with bringing those killers to justice. Even as he grew up,
went to school, fell in love, and got married, the thought has never been far from his mind: no child should grow up in a world where killers are on the loose.
Sean is madly in love with his wife, Megan, partly because in her he sees hope for the future. She is beautiful, smart, organized, competent. She works as a PR representative for a clean energy company. He roots for her, singing her
praises every chance he gets.
The only trouble is, Megan can’t have kids. She and Sean have tried everything. Their marriage is under strain. Sean begins to fear the worst: they have no future. Megan leaves on a long business trip while Sean loses himself in
research for his latest story. A new killer is on the loose, active in multiple states and targeting women. For Sean, it feels personal. If he can crack this case and bring this person to justice, the world will be a better place.
Sean works and works, putting the pieces together. He has a contact at the FBI who feeds him clues. The killer has killed again, in yet another state. Sean notices a pattern, so awful he doesn’t want to admit it to himself. But the
facts are there: every murder has happened in a place his wife has traveled to for work. Sean can’t believe it. His lovely wife. A serial killer?
But then he starts to think. Megan is often cold and distant. She had a troubled childhood. She doesn’t have many friends. She is obsessively clean. Sean faces the inevitable. He has to turn her in.
Megan comes home. Sean doesn’t get a chance to confront her. The minute she comes in the door, she throws herself in his arms. She’s pregnant. Pregnant! A baby on the way. Sean couldn’t be happier.
Later, in his office, going over his research, Sean tries to bend the data, to make it say anything else. It refuses to change. He makes a decision, for the sake of his child, for the sake of the future. He will cover up his wife’s
crimes until their baby is safely born.
Alan Winter is the lead FBI agent in the hunt for the new serial killer. He is a model agent, with immaculate scores on every exam. His track record is perfect. He’s going to bring this bad guy down because justice must be
served.
Alan is hampered by his team, a bunch of lazy dopes who have seen too many movies. They seem more interested in who will play them in the TV show about the case than in actually catching the killer. Alan needs someone as serious as he is,
and he needs to find that person quickly—before the killer kills again.
Fred, one of the hapless underlings, mentions his friend Sean, a journalist who has written extensively about serial killers. Alan gives Sean a call and ropes him into the investigation. Sean is happy to help, maybe a little too happy.
Alan chalks it up to civilian enthusiasm.
Alan and Sean pool their resources and glean what information they can. All of the victims were young women—nothing new there. The victims were various ethnicities—that’s odd, given that most killers stay within their
own ethnic group. The victims were killed in major cities, but spread out between states. Sean keeps mum, but Alan finds this intriguing. He deduces the killer must travel by air and begins to stake out airports.
Megan is off on another business trip with her coworker, Michal. Everywhere she goes, she glows with happiness, so much so that Michal comments on it. Megan shrugs it off. She’s just jazzed about work. Sean texts her constantly,
trying to keep tabs, hoping she doesn’t go off the deep end. At home, he tries to foil Alan in whatever ways he can: offering incorrect facts, suggesting alternative explanations, slowing down the investigation. Megan returns, casually mentions that she was searched at the airport. Sean is frantic. Megan suggests they have Alan over for dinner. Sean tries to change her mind, but she is insistent.
Alan is stiff and awkward in their home. Sean laughs loudly at his own jokes. Megan is the perfect hostess, polite, charming, warm, friendly. Honestly, Sean can barely recognize her. Alan picks up on Sean’s discomfort and
confusion and leaves thoughtful. The next day, he asks Fred to look into Sean’s background.
Megan’s ultrasound. Sean is transported with joy. A new human. A new start for all of them. The doctor is slightly worried that the baby isn’t developing normally. Asks them to schedule another visit, very soon. They leave
with a mixture of joy and fear. What if something’s happened to the baby?
Megan has yet another business trip. Sean asks her to stay home this time, but she is determined to go. She has to stay busy. Keep her mind off things. Sean is just beginning to calm down when she texts him: Bleeding. Oh, no, she’s
miscarried. He calls her, calls her again, but she doesn’t pick up. No, no, no. Sean wonders if he should tell Alan, confess the whole thing and try to stop Megan. He stays up all night, wondering, deciding.
Next morning, Alan calls him. There’s been another murder, they just found the body. Yes, the same killer. Yes, in the same city Megan was staying in. And there’s more: the body was found in the alley behind her hotel.
Now it’s all over for Sean. There’s nothing left for it now. He has to turn her in. He’s at home, psyching himself up, and Megan shows up. Out of the blue. Not due home for two days. She left the conference early. She
had to see him. Had to tell him. She saw a doctor. The baby’s fine. Developing normally. Nothing to worry about. Sean destroys any evidence he has about the latest murder. He won’t turn Megan in, not till the baby is born. He
parries Alan at every turn, bringing up every shred of evidence he can think of that will lead him off the right track.
Alan, meanwhile, is putting the pieces of the puzzle together. The killer is a woman. A woman who travels a lot. A woman who was probably staying in the hotel and left the next day. He considers sharing his thoughts with Sean, but
something stops him. They meet again, and Alan is cagey. Sean suspects that something is up. He starts to wonder if he needs to take this into his own hands. He knows where Alan lives. He knows Alan’s schedule. He could make Alan
disappear.
At home, Megan has Michal over to tell her the good news. “I’m pregnant!” Michal is suitably excited. The two chat and gossip about Megan being a mom. What about work? Megan will probably quit, but it’s worth it,
right? Raising a child, bringing new life into the world. The two stay up late, talking and sharing.
Alan and Sean are at the FBI office, working late, digging into the files. Alan decides to knock off, get some sleep. Sean pretends to drive home, then turns around and follows Alan back to his apartment. Alan goes inside.
Sean sits in his car, waiting, trying to get ready for what he has decided must be done. For the sake of his wife. For the sake of their child. He is about to get out of the car when his
phone rings. Alan. Sean picks up, trying to sound sleepy. Alan says he’s figured it out. The killer is a woman. She works for a clean energy company. She was in town for a conference. She kills women out of envy. She always
kills on the last day she’s in a city, then leaves. The latest victim was killed on the last day of a clean energy conference. Hold on, says Sean. That can’t be. My wife was home that day. She left the conference early...
Your wife? Megan’s not the killer, Alan says. The prime suspect is a woman named Michal...
Sean speeds home as fast as he can, dialing Megan. Michal has gone into the kitchen for a glass of wine. Megan’s phone is on the counter. Michal tosses it in the garbage, casually selects a chef’s knife from the block on the
counter. Megan is in the bathroom. Michal stands in the living room, waiting, knife in her hand. Megan steps into the room. Her eyes go wide as Michal rushes towards her. Sean bursts into the room and takes her down. She slashes him. Megan
picks up a chair and knocks her senseless. Alan pulls into the driveway and rushes into the house, gun drawn. He finds Sean covered with blood, embracing his wife. Sean Stephens, you are under arrest.
Sean moves numbly through his trial, not trying to argue his innocence. He didn’t know Michal was the killer, but he aided and abetted her all the same. Megan is cold, sitting silently in the courtroom. Sean gets ten years. He and
Megan sit on opposite sides of glass in the visiting room. Megan presses a picture of their son onto the glass.
