Sheena is nearly mauled to death by a dangerous jungle cat, but is saved at the last minute by a kindly doctor.
In a page from "The Hawk" in the same issue, Velvet, the ship's sexy first mate gets ko'd by a sneaky vagabond who plots to bring the ship to Japan (yeah, it was wartime, and if anyone is offended by period "sneaky jap" ethnic stereotyping , skip this one...)
