The Inquisitor

A spectacularly original thriller about a professional torturer who has a strict code, a mysterious past, and a dangerous conviction that he can save the life of an innocent child
Geiger has a gift: he knows a lie the instant he hears it. And in his business—called "information retrieval" by its practitioners—that gift is invaluable, because truth is the hottest thing on the market.
Geiger's clients count on him to extract the truth from even the most reluctant subjects. Unlike most of his competitors, Geiger rarely sheds blood, but he does use a variety of techniques—some physical, many psychological—to push his subjects to a point where pain takes a backseat to fear. Because only then will they finally stop lying.
One of Geiger's rules is that he never works with children. So when his partner, former journalist Harry Boddicker, unwittingly brings in a client who demands that Geiger interrogate a twelve-year-old boy, Geiger responds instinctively. He rescues the boy from his captor, removes him to the safety of his New York City loft, and promises to protect him from further harm. But if Geiger and Harry cannot quickly discover why the client is so desperate to learn the boy's secret, they themselves will become the victims of an utterly ruthless adversary.
Mesmerizing and heart-in-your-throat compelling, Mark Allen Smith's The Inquisitor is a completely unique thriller that introduces both an unforgettable protagonist and a major new talent.
