He Who Whispers

He Who Whispers is a mystery novel (1946) by detective novelist John Dickson Carr. Like Many of the works by this author feature so-called impossible crimes (for the most part, falling into the category of the locked room mystery). In this case, the novel falls into a smaller category of Carr's work in that it is suggested that the crime is the work of a supernatural being (here, a vampire). The detective is Dr. Gideon Fell, who ultimately uncovers a rational explanation for the novel's events.
