The Riddle of the Seventh Person

A retired judge is murdered, leaving behind a group photo of seven people and the letter G. This isn't a suicide note. It's the killer's first riddle for the detective. Seven riddles, six suspects, five layers of false solutions. Each riddle solved takes the truth one step further away. Because the killer isn't here to kill. He's here to play chess. And the detective is the pawn on the board. “The closer you get to the truth, the farther the truth moves away from you.”
