The Affair at the Semiramis Hotel

An amateur raconteur and a perceptive French detective become drawn into a baffling episode after a nervous young man describes leaving a grand hotel's masked ball in a state of alarm and confusion. The account of costume exchanges, a helpful stranger, and an abrupt unsettling absence prompts a careful inquiry that uncovers layers of artifice, drugging, and concealed movements behind the hotel's glittering surface. The investigation reconstructs the evening through observation and reasoning, exposing criminal intentions hidden beneath public gaiety and contrasting the hotel's visible luxury with a secretive, menacing underworld before resolving the mystery through methodical detection and psychological insight.
