Jumbo Comics #24

Sheena falls victim to a spitting cobra's venom while fighting a leopard, and Bob Reynolds races desperately to fetch Dr. Mohammed Bey from the coastal city of Mombasa—but time is running short, and not everyone wants the doctor to reach her in time. With the signal drums calling Africa's greatest witch doctors and warriors to Sheena's aid, three fugitives from the law see an opportunity to plunder the undefended villages while everyone's attention is elsewhere.

When a ferryboat captain witnesses something sinister being dumped into the river, Inspector Dayton arrives to find a gruesome discovery: a torso bearing two identical severed heads—evidence that points to the circus's famous Two-Headed Lady. As Dayton investigates the twins Mitzi Dolan and Flora Dolan, he narrows his suspects to three circus performers who each claim to have been with one of the women the night she died, but a piece of evidence hidden in the wrong tent and a deadly fall will force the inspector to uncover the real killer before the truth dies with the guilty.
