Dead of Winter — William H. Hallahan

Edgar Award Finalist for Best First Mystery: “Eerie . . . A book you will gulp down” (The New York Times).
 
Lyons, Basche, and Tyler -- three ordinary guys -- find their fourth poker night partner, Reece, fatally beaten on the floor of his apartment. Reece was a quiet, unassuming fellow but he had one outstanding trait: his fabulous memory. On Friday nights he could recall every card that was played. Yet his final slurred words were: “I don't remember.”
 
His three remaining friends, shocked by the indifference of the police, form their own tribunal of retribution: to find the people who had used Reece so ruthlessly and who had disposed of him in the same way; to deal with the assassins with a like kind of justice; and to ferret out the “lost” information that cost Reece his life. Their motivation and their mission culminate in an unforgettable tale of vengeance and its consequences.
