The Demon Laughs (142-145)
By Chuck Dixon, Jim Aparo, and John Cebollero
Ra's al Ghul recruits the Joker in his latest scheme to kill off ninety-five percent of the world's population, and the Ace of Knaves is all too happy to accept. An attempted double-crossing on The Joker's part, however, results in him being gunned down by Ra's' followers, and if Batman is to have a hope of stopping Ra's from spreading The Joker's virus, he must save the life of his greatest foe.
