The Double-Thirteen Mystery. Dr Hailey Mysteries. Illustrated, livre ebook

The Double-Thirteen Mystery by Anthony Wynne is a classic locked-room detective novel featuring the keen intellect and psychological insight of Dr. Eustace Hailey. First published in the 1925 , this mystery is a standout example of Golden Age detective fiction—full of atmosphere, suspense, and a seemingly impossible crime.
The mystery begins with the shocking death of Sir John Burslem, found murdered in his study behind locked doors and shuttered windows. The only clue? A cryptic arrangement of playing cards—two sets of thirteen—left carefully on the table. The baffling symbolism, along with the absence of a weapon or any sign of intrusion, leaves the local authorities mystified.
Dr. Hailey is called in to unravel the case. As he investigates, he discovers layers of deception, a long-buried scandal, and a cast of suspects whose motives are as intricate as the crime itself. Every detail—from the positioning of the cards to the victim's shadowy past—holds a clue to the chilling truth.
With its ingenious plot, eerie clues, and satisfying resolution, The Double-Thirteen Mystery is a compelling read for fans of Agatha Christie, John Dickson Carr, and traditional British whodunits. A true gem of vintage crime fiction.
