An elegantly plotted detective mystery that unwinds one of the most astonishing literary puzzles ever written, from the master of mystery.
In a rocky cove in the bay of Hakata, the bodies of a young and beautiful couple are discovered. Standing on the cold beach, the police see nothing to investigate: the flush of the couple's cheeks and the empty juice bottle speak clearly of cyanide, of a lovers' suicide. But in the eyes of two men, Torigai Justaro, a senior detective, and Kiichi Mihara, a young gun from Tokyo, something is not quite right. Together, they begin to pick at the knot of a unique and calculated crime.
