Set in Europe in the 1920s, this is the story of Trey, a boy whose life is dominated by his collection of comics telling the tales of super-sleuths and daring detectives. Trey has joined his father, a Chicago businessman, on a trip to Constantinople and, when they board the Orient Express, Trey is thrilled to think that, just like in the comics, they are being followed by a mysterious stranger. Matters take a more sinister turn, however, when Trey's father goes missing and Trey is plunged into the dangerous, real-life world of espionage to try and find him.
