in DC's Elvira's House of Mystery (1986–88). In 1985, the characters were revived by writer Alan Moore, who introduced them into his Swamp Thing series in issue #33, retelling the Swamp Thing's original origin story from a 1971 issue of House of Secrets. Gary Cohn and Dan Mishkin included them in the pages of Blue Devil in 1986. Jamie Delano also occasionally used them in a cameo role in his title Hellblazer. In The Sandman In Gaiman's Sandman universe, the biblical Cain and Abel live in the Dreaming at Dream's invitation. This is based on the verse in the Bible which says that Cain was sent to live in the Land of Nod. They live as neighbors in two houses near a graveyard: Cain in the broad House of Mystery and Abel in the tall House of Secrets.

He has been described by other characters as sounding "just like Vincent Price". Gaiman's Abel is a nervous but kind-hearted man. He also has a stammer. He is somewhat similar in appearance to Cain, with a tufty beard and hair that comes to points above his ears, though his hair is black rather than brown. He is shorter and fatter than Cain, with a more open face. It is eventually learned that the only time he does not stutter is when he is telling a story or when he is dead. Cain kills Abel frequently and in many brutal ways, whereupon Abel later returns to life. He often expresses hope for a more harmonious relationship with his brother. Cain and Abel own a large green draconic gargoyle named Gregory, who also made his debut in House of Mystery #175. In the first appearance of the characters in Sandman, issue #2, Cain gives Abel an egg that soon hatches into another gargoyle, a small golden one. Abel names the gargoyle "Irving". but Cain insists that the names of gargoyles must always begin with a "G.", and Abel (after another death and resurrection) renames the gargoyle "Goldie", after an invisible/imaginary friend to whom Abel told
