Short Synopsis
From the authors of the "true crime classic" Notes on a Killing comes the harrowing story of the games that couples play—and what happens when role-playing becomes a deadly reality.

Full Synopsis
Was murder part of the game?

Seventeen-year-old Kat McDonough grew up with theater in her blood—and a penchant for make-believe. More than a decade older, Seth Mazzaglia was well known in the community theater circle of Portsmouth, New Hampshire. He, too, had a rich inner life—and he soon had Kat convinced that they were soul mates.

To intensify their bond, Seth lured Kat into a world of violent sex and role-playing, where she was his slave. But even that wasn't enough to satisfy his ravenous appetites.

Enter Lizzi Marriott, the new girl in town. And when she accepts an invitation to Kat and Seth's apartment, she will never be seen again . . .

“This book does much more than tell a crime story; Flynn and Lavoie gift the reader with an inside look at human frailty and the ways that a skilled sociopath can manipulate others toward the desires of their dark hearts.” ---Anthony Flacco, New York Times bestselling author of Impossible Odds

“Twisted and intriguing . . . Kevin Flynn and Rebecca Lavoie do a masterful job tackling a disturbing case.” ---Shanna Hogan, New York Times bestselling author of Picture Perfect: The Jodi Arias Story

“Flynn and Lavoie expertly layer on stunning, devastating detail to explain the inexplicable—a case that had the media stumped for months. I couldn’t stop reading, and neither will you.” ---Robert Kolker, author of Lost Girls
