Mysteries of Unexplored Worlds #30

This anthology issue contains multiple stories investigating the unexplained. The cover story depicts scientists and explorers confronting a sea monster, with one character dismissing the encounter as a publicity stunt. "It's a Small World" tells of a man who creates an intricate miniature world complete with model soldiers and tiny towns, only to discover his creation has become unnervingly real. "Three Thoughts" presents a narrative framed by Dr. John Boyle, who works with the Saxon Foundation investigating the supernatural and paranormal, describing an investigation into alleged telepathic communication between two brothers in Paris. The final visible story features a character named Felix encountering a sea creature and clashing with photographers over proof of the monster's existence.
