From the author of the acclaimed The Girl with a Clock for a Heart – hailed by the Washington Post as crime fiction’s best first novel of 2014 – comes a devious tale of psychological suspense involving sex, deception, and an accidental encounter that leads to murder that is a modern reimagining 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 coconspirators 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.
