Plot summary
Ichabod and Katrina attempt to reconcile their marriage, but are faced with a murder investigation when the body of an art restorer is found in the hanged man position. Katrina remembers her friend Abigail Adams ( Michelle Trachtenberg ) speaking of similar murders in 1781, and of how they remain unresolved despite her best efforts. They learn that the murderer is a man called James Colby, an artist and serial killer who was only stopped when Abigail used herself as bait to imprison him inside his final, unfinished painting. Ichabod and Katrina enter the painting and free the missing man, but also give Colby an opening to complete his painting and escape. Abbie destroys the painting, erasing Colby's soul from existence. Irving is mysteriously resurrected without his memories, which they initially try to hide from his family. Abbie, however, eventually reveals the truth to his wife.
