imprint began a new ongoing series in May 2008, written by Lilah Sturges and Bill Willingham. It features at least one different story each issue, told by people trapped in a "purgatory-like house". The series ended in October 2011 with issue #42. Two Annuals were also published. The House The House of Mystery exists as a location in the DC Universe simultaneously just north of Louisville, Kentucky, where it was built and almost immediately abandoned by one Col. Braitwaithe before the American Civil War, and in the Dreaming. Very little is known about the House of Mystery in general. The architecture is indeterminate and changes periodically. The same holds true for the inside of the House: the rooms constantly shift and one never enters the same room twice. The House of Mystery lies in the same graveyard as the House of Secrets, its companion. Cain lives in the House of Mystery, whereas Abel resides in the House of Secrets. Cain is not the only person to have resided within the House; in addition to boarders, including Mister Mxyzptlk, Elvira, Mistress of the Dark took shelter within the House. Her brief stay in the House of Mystery is notable for two reasons: first, the House of Mystery is established as being the same House throughout its publication history. Three distinct personalities of the House are shown: the original horror House of Mystery, a dark humor "House of Weirdness"-style which harkened back to Cain's stint in Plop!, and the current version of the House of Mystery in Kentucky. The second reason is the timing of Elvira's stay. She took up residence during the Crisis on Infinite Earths. Elvira, tasked by the House of Mystery to find Cain, took over his role of host for a brief period, while Cain was relegated to being the butt of her jokes during occasional cameos. The House of Mystery possesses sentience, along with mystic powers. It has possessed someone before and merged with the House of Secrets briefly. This ties into the constantly shifting appearance of the House of Mystery. It was torn down in the metafictional The House of Mystery #321, but its existence was restored during the Crisis. Batman entered the house in The Brave and the Bold #93, tripped on a floorboard, and would have been shot had his pursuer's gun not jammed. He never actually met Cain, who instead narrates a story
