On April 16, 1897, cashier Joseph A. Stickney was murdered during a daring daylight robbery of the Great Falls National Bank in Somersworth, New Hampshire. The frenzied investigation that followed, crossed state and national borders resulting in the arrests of Joseph Kelley, a resident of Somersworth with peculiar habits. Joseph E. Kelley confessed to the murder, leaving the court to decide whether his actions were driven by a mental disorder, whether he was feigning mental disability, or whether Kelley had in fact made a contract with the devil.
