HELLBLAZER (1988) #140

A 4-issue sequence of self-contained stories by different artists begins with the claustrophobic terror of "Locked." Imagine a room that was irrevocably stained by the acts of bottomless evil that transpired within it, a room that was so impregnated with hate and death that anyone who entered would struggle not to succumb to its power. Now imagine John Constantine locked in that room with the man who committed those atrocities in the first place. The only way out is for one of them to crack.
