Men of Mystery Comics #54

In "The Plundering Pooch," wealthy and suspicious Bruce Brinton finds an unlikely companion in a small, scruffy puppy—though his hardened exterior hides a surprising fondness for the little dog. Unbeknownst to him, the pup is secretly wired by Hacker Kane’s crew to track the elusive Terror Twins, turning an innocent bond into a high-stakes game of cat and mouse.

In "null," Colonel Withers pushes his camel corps into the desert on a mission to capture the elusive raider Sharane, dismissing Terry’s suggestion to enlist the legendary Desert Panther. When the mission turns dire and the men are taken, Terry escapes, dons the Panther’s mask, and rallies the Panther’s forces to free Withers and bring Sharane to justice.
