A devious tale of psychological suspense perfect for fans of Paula Hawkins’ The Girl on the Train—and is soon to be a major movie directed by Agnieszka Holland.

In a tantalizing set-up reminiscent of Patricia Highsmith’s classic Strangers on a Train… On a night flight from London to Boston, Ted Severson meets the stunning and mysterious Lily Kintner. Sharing one too many martinis, the strangers begin to play a game of truth, revealing very intimate details about themselves. Ted talks about his marriage that’s going stale and his wife Miranda, who he’s sure is cheating on him. Ted and his wife were a mismatch from the start—he the rich businessman, she the artistic free spirit—a contrast that once inflamed their passion, but has now become a cliché.

But their game turns a little darker when Ted jokes that he could kill Miranda for what she’s done. Lily, without missing a beat, says calmly, “I’d like to help.” After all, some people are the kind worth killing, like a lying, stinking, cheating spouse. . . .

Back in Boston, Ted and Lily’s twisted bond grows stronger as they begin to plot Miranda's demise. But there are a few things about Lily’s past that she hasn’t shared with Ted, namely her experience in the art and craft of murder, a journey that began in her very precocious youth.

Suddenly these co-conspirators are embroiled in a chilling game of cat-and-mouse, one they both cannot survive . . . with a shrewd and very determined detective on their tail.

“The inventive Mr. Swanson never lets the willing reader down. With The Kind Worth Saving, he surpasses his own high standard.” — Tom Nolan, Wall Street Journal

In this spectacularly devious novel by New York Times bestselling author Peter Swanson, a private eye starts to follow a possibly adulterous husband, but little does he know that the twisted trail will lead back to the woman who hired him.

There was always something slightly dangerous about Joan. So, when she turns up at private inves­tigator Henry Kimball’s office asking him to investigate her husband, he can’t help feeling ill at ease. Just the sight of her stirs up a chilling memory: He knew Joan in his previous life as a high school English teacher, when he was at the center of a tragedy.

Now Joan needs his help proving that her husband is cheating. But what should be a simple case of infidelity becomes much more complicated when Kimball finds two bodies in an uninhabited suburban home with a FOR SALE sign out front. Suddenly it feels like the past is repeating itself, and Henry must go back to one of the worst days of his life to uncover the truth.

Is it possible that Joan knows something about that day, something she’s hidden all these years? Could there still be a killer out there, someone who believes they have gotten away with murder? Henry is determined to find out, enlisting help from his old nemesis Lily Kintner—but as he steps closer to the truth, a murderer is getting closer to him, and in this hair-raising game of cat and mouse only one of them will survive.

A newlywed librarian begins to suspect the man she married might be a murderer—in this spectacularly twisty and deviously clever novel by Peter Swanson, New York Times bestselling author of The Kind Worth Killing and Eight Perfect Murders.

Martha Ratliff conceded long ago that she’d likely spend her life alone. She was fine with it, happy with her solo existence, stimulated by her work as a librarian in Maine. But then she met Alan, a charming and sweet-natured salesman whose job took him on the road for half the year. When he asked her to marry him, she said yes, even though he still felt a little bit like a stranger.

A year in and the marriage was good, except for that strange blood streak on the back of one of his shirts he’d worn to a conference in Denver. Her curiosity turning to suspicion, Martha investigates the cities Alan visited over the past year and uncovers a disturbing pattern—five unsolved cases of murdered women.

Is she married to a serial killer? Or could it merely be a coincidence? Unsure what to think, Martha contacts an old friend from graduate school for advice. Lily Kintner once helped Martha out of a jam with an abusive boyfriend and may have some insight. Intrigued, Lily offers to meet Alan to find out what kind of man he really is . . .but what Lily uncovers is more perplexing and wicked than they ever could have expected.
