“One night, returning home, much intoxicated, from one of my haunts about town, I fancied that the cat avoided my presence.” So begins the madness of the alcoholic narrator in Edgar Allan Poe’s classic “The Black Cat” — a tale of violence, guilt and a cat returning from the grave. It’s fiendishly fitting inspiration for the Poe Museum’s September Unhappy Hour, which features a cash bar and music by local favorites Goldrush. Afterward, the Poe Museum will screen “The Persistence of Poe,” a new documentary by Christine Stoddard and David Fuchs about Poe’s life in Richmond. The Unhappy Hour takes place at the Edgar Allan Poe Museum on Thursday, Sept. 27, from 6-9 p.m. $5 suggested donation. poemuseum.org.
