Batman #268

In "Murder Masquerade!", Batman confronts a deadly mystery unfolding across Gotham’s streets and rooftops, beginning with a violent camel stampede at the pier and escalating to a murder at the Sports Arena. With the enigmatic "Sheikh" leaving a trail of chaos and a burnoose-clad assassin on the loose, Batman and Robin must piece together the clues—despite injury and mounting pressure—before another partner falls. Written by Denny O'Neil and illustrated by Irv Novick, with inks by Tex Blaisdell and letters by Joe Letterese, this 1975 tale features a striking cover by Ernie Chan.
