Don't you love "the nameless detective"?
Labyrinth is Mr. Pronzini's most elaborate plot, and one that will probably keep you fascinated up until the last few pages. It starts simply enough. Nameless is called in by his friend, police lieutenant Eberhardt, when a dead woman's purse contains Nameless's business card. Nameless has never met her, and cannot make a connection. Next, Nameless is hired to track and protect a disturbed man, Martin Talbot, who may be harmed by the husband of a woman who died when Talbot's car collided with theirs after Talbot fell asleep at the wheel. Despite keeping a close tail, things go horribly wrong. Convinced that Talbot needs his help, Nameless tries to figure out what really happened. In the process, he learns that the son of the woman Talbot killed was engaged to the young woman who had his card. What could this mean? From there, the connections between the Cardings and Talbot's family quickly multiply.
Most people will not be able to unravel this mystery. It contains a lot of unexpected elements and delicious complexity. From an amateur sleuth reader's point of view, this book is a delight for that reason.
