Criminal Macabre: A Cal McDonald Mystery is a comic book series starring Cal McDonald, an antihero American comic book character created in 1990 by Steve Niles (writer). The character's adventures have been published by Dark Horse Comics and later IDW Publishing.
Cal himself is akin to John Constantine, a DC Comics paranormal detective. He takes illicit drugs, and befriends a network of ghouls to assist him in his cases. Policemen do not really care to be involved with Cal.
