After being declared criminally insane, the world's deadliest assassin, Deathstroke, is committed to the infamous Arkham Asylum! ENTER THE ASYLUM. Slade Wilson is the world's deadliest assassin. That makes him ruthless, dangerous, perhaps even evil. But criminally insane? Neither friend nor foe has ever thought so before. Until now. Captured, tried, and sentenced, Deathstroke now finds himself the newest inmate of Arkham Asylum. It's Gotham City's infamous ward for the craziest criminals the world has ever seen—Two-Face, the Riddler, Scarecrow, Mr. Freeze, the Mad Hatter, and more. It's the most dangerous place on Earth. And now Slade is locked inside. To survive with his life and his sanity intact, he'll have to learn to work the system, test the asylum's defenses, and either recruit or defeat any super-villain who stands in his way. His body, his mind, and his very grip on reality itself are in peril at every turn—even as his children, Rose and Jericho, fight their own battles to free their father. It's the greatest challenge of Deathstroke's career. Can he escape the asylum? And what will be left of him if he does? Find out in Deathstroke: Arkham, as legendary writer Christopher Priest and artist Fernando Pasarin take Slade to a place he's never gone before—and may never leave again! Collects Deathstroke #36-40.
