Holyoke One-Shot 10 - Captain Stone Comics #10

Captain Stone, a marine investigator equipped with a special helium-filled diving suit allowing him to work at 400 feet instead of the usual 150 feet, investigates a sunken wreck off the China shore. The issue contains multiple stories, including a heist narrative where criminals rob a woman named Betty of her jewels, and an aviation adventure in which a pilot and crew survive a plane crash and devise a plan to raid enemy aircraft with their own bomber. A third story involves a mysterious figure called Lonna and an expedition to Shangrila, where characters encounter an otherworldly threat represented by a strange artifact discovered at the crash site.
