Mounted police trained to track the criminally insane must hunt serial killers in this volume featuring the first four books in the Special X thriller series. The Special X team of the Royal Canadian police are experts at decoding the criminal mind—and hardened by years of confronting the most heinous of murderers. From serial killers driven by demons as dark as Jack the Ripper’s to psychopaths with a penchant for gruesome displays of their victims, no evil is too sinister for the agents of Special X. At least, not yet. . . . This collection features the first four thrillers of the Special X series: Headhunter, Ripper, Bed of Nails, and Hangman Praise for the Special X series “Michael Slade’s books are blood-chilling, spine-tingling, gut-wrenching, stomach-churning, and a much closer look at the inside of a maniac’s brain than most people would find comfortable, but always riveting.” —Diana Gabaldon, #1 New York Times–bestselling author of the Outlander series “Extraordinarily vivid. A thinking man’s Texas Chainsaw Massacre.” —The Vancouver Sun “Highly enjoyable.” —Time Out, London “Slade knows psychos inside out.” —Toronto Star “A get-under-your-skin thriller with machine-gun dialogue and impressive real-world research. It’s one heck of a ride.” —CNN.com “As always with Slade, a cracking good detective story.” —Anne Perry, New York Times–bestselling author of the Thomas Pitt series “Murder with gore galore, and a killer who enjoys his hobby.” —The Globe and Mail (Toronto) “Michael Slade is a writer who clearly knows how to tell a story and make it real.” —Robert McCammon, New York Times–bestselling author of Swan Song and the Matthew Corbett series
