Three Graves

The golden age of detective fiction gifted us many star names. The works of writers such as Agatha Christie, Gilbert Chesterton, Earl Stanley Gardner, Rex Stout, developed and refined the detective genre; their novels, unequivocally recognized as classics, are still... loved by readers today and serve as a benchmark of quality for subsequent generations of authors of detective stories. A worthy place in this galaxy rightfully belongs to John Dickson Carr (1906–1977) — a virtuoso master of perfectly constructed "impossible crimes in a locked room."
In 1933, in the novel "The Witch's Cabin," John Dickson Carr first introduced the amateur detective Dr. Gideon Fell to the public. Then, in the novel "Three Graves" (1934), also published under the title "The Hollow Man," Dr. Fell addressed the reader with the legendary "Lecture on the Locked Room," unexpectedly adding to his glorious achievements an unparalleled investigation into the mechanics of one of the key plot schemes of detective literature.
The mysterious murderer leaves no traces and disappears from the crime scene, as if... a ghost. It is time to find out whether any mystery is beyond Dr. Fell's capabilities, or even his ingenious mind will have to concede when it comes to mysteries of otherworldly origin?
