From #1 New York Times bestselling author Lisa Jewell, three women are connected by one man in this "gripping, shocking, masterful" (Freida McFadden, #1 New York Times bestselling author) thriller.

He's the perfect man. It's a perfect lie.

Nick Radcliffe is a man of substance and good taste. He's exactly what newly widowed Nina Swann needs in her life. But to Nina's adult daughter, Ash, Nick seems too slick, too polished, too good to be true. When Ash begins digging into his past, she finds a trail of unsettling coincidences.

Martha lives in a neighboring town with her infant daughter and devoted husband Alistair. But lately, Alistair has been traveling more and more frequently for work, disappearing for days at a time, and Martha can't shake the feeling that something isn't right.

Nina, Martha, and Ash have no idea they are on a collision course with a shocking truth. And all three are about to wish they had heeded the same warning: Don't let him in.
