Edgar Wallace, author of „The Lone House Mystery", was a celebrated British author in the early twentieth century. Over 160 of his novels have been made into films, and he is known especially for his part in writing the story for the movie „King Kong". The dead man was rich. In life he lived in a lonely house by a river. In the earth outside it is the imprint of a bare foot. His secretary, with whom he was having an affair, is locked in a room. The key is in the dead man's pocket. Superintendent Minter considers it a most queer and unsatisfactory case. A thrilling, thoroughly intriguing tale of double murder and love. This collection also includes the following short stories: „Clues", „The Sooper Speaking", and „Romance In It".
