Bat Wing

A London private detective and his friend investigate a series of strange assaults and a lingering sickness reported by a colonel who links the events to voodoo rites and a preserved vampire bat wing. Their inquiry moves between country estates and city rooms, combining interviews, police questioning, forensic experiments, and the study of local superstition. Multiple suspects and hidden motives emerge as inspectors and witnesses cross-examine testimony, and a woman's confession helps to clarify secrets surrounding the attacks. The narrative resolves the apparent supernatural phenomena by revealing human designs, the method behind the creeping illness, and the ways fear was exploited.
