Named "Bat-Man" in the story.

This is an exact reprint of the story as originally published, rather than the redrawn and censored version which appears in some prior reprint editions. The murder victim on page 2, panel 2 does have the knife jutting from his back.

According to Will Murray and Anthony Tollin, the November 1, 1936, Shadow novel Partners in Peril, written by Theodore Tinsley, was Bill Finger's inspiration for this story.

According to DSK of the Vallely Archives blog, and Robby Reed of the Dial H for Blog, the art in this issue is inspired by Henry Vallely's Gang Busters in Action (Big Little Book 1451) and Tom Lovell's art in Partners in Peril.
