The Case of Jennie Brice is a crime novel by the American writer Mary Roberts Rinehart (1876–1956) set in 1904 in Allegheny, Pennsylvania, which has been a part of the city of Pittsburgh since 1907. A blood-stained rope, and towel, and a missing tenant, Jenny Brice—all of which convince Mrs. Pittman that a murder has been committed in her boarding house. But without a body, the police say there is no case. Pittman tries to ferret out the killer by using the key to Jennie's apartment to investigate.
