Beware the Creeper began in the March/April dated, Showcase #73 in 1968, in a story plotted and drawn by Steve Ditko, with Don Segall assisting with the dialog.
DC's policy at the time was to give a character a single appearance in Showcase as an introduction before launching their series.
Beware the Creeper was cancelled after six issues, the victim, per columnist and artist Fred Hembeck, of "bean-counters [who] were a little quick to yank the rug out from underneath a new series during that particular stage of DC's history...."[2] The storyline started in the six issues of Beware the Creeper would eventually be concluded seven years later in Super-Team Family #2, published in 1975.
Set in 1925 Paris, Beware the Creeper tells the story of Judith and Madeline Benoir, twin sisters, one a surrealist painter, the other a playwright.
The situation quickly spirals out of control as the Arbogasts begin to seek revenge in turn, and lives are eventually lost.
