When Wagner first serialized Devil by the Deed as a backup in his critically acclaimed title Mage, its innovative storytelling techniques, philosophical undertones, and charismatic anti-hero ignited a devoted following. Introducing Hunter Rose as the brilliant, twisted assassin Grendel, it gave birth to what would become a centuries-spanning epic exploring the roots and consequences of violence. This influential tale has been collected only twice in the past twenty years, quickly selling out each time. Now, for the first time in hardcover, Dark Horse presents the book that brought one of the most popular alternative comics characters to life and marked the auspicious arrival of one of the greatest visionaries of modern comics!

For years, the life of the original Grendel, Hunter Rose, has been accessible only through his private journal, but there is a secret too terrible for even its pages, and a section of the journal is missing. Behold the Devil follows Rose through this lost period early in his criminal career, as he is under scrutiny not only by the police and media, but also by the prying eyes of an unseen - possibly supernatural pursuer. Unusually shaken and paranoid, the criminal mastermind is forced to take steps that redefine the evil of the entity known as Grendel!
