Detective Comics (Detective Comics Vol. 3 #1103)

Gotham's newest villain, the Lion, has lain in wait, much like his namesake, choosing now to strike the Dark Knight. Meanwhile, the infection coursing through Batman's veins continues to work its way into his central nervous system, leaving him vulnerable on two fronts.

Poisoned and alone, Batman has run out of places to look for help... but maybe all he needed to do was look up. “The Courage That Kills” continues in this can't-miss issue guest-starring Superman!
