The Spectacular Spider-Man #109

Synopsis

Spider-Man and Daredevil scour the city looking for the Sin-Eater. The villain shows up at the Bugle looking to kill Jameson and Peter takes him out easily. The captured Sin-Eater turns out to be a copy-cat criminal and, when Spider-Man and Daredevil investigate his apartment, discover that he lives next door to Sgt. Carter, the real Sin-Eater. Realizing that Jameson is a legitimate target, Spider-Man calls his house and Betty answers in a panic as Sin-Eater has a gun in her face.
