The Last Stone: A Masterpiece of Criminal Interrogation

The true story of a cold case, a compulsive liar, and five determined detectives, from the number-one New York Times best-selling author and master journalist (The Wall Street Journal). On March 29, 1975, sisters Katherine and Sheila Lyons, ages 10 and 12, vanished from a shopping mall in suburban Washington, DC. As shock spread, then grief, a massive police effort found nothing. The investigation was shelved, and the mystery endured. Then, in 2013, a cold case squad detective found something he and a generation of detectives had missed. It pointed them toward a man named Lloyd Welch, then serving time for child molestation in Delaware. The acclaimed author of Black Hawk Down and Hue 1968 had been a cub reporter for a Baltimore newspaper at the time of the original disappearance, and covered the frantic first weeks of the story. In The Last Stone, he returns to write its ending.

The Last Stone recounts a masterpiece of criminal interrogation, and delivers a chilling and unprecedented look inside a disturbing criminal mind.…
