Boy Scouts in the North Sea; Or, the Mystery of "U-13"

A patrol of young American scouts traveling home from covert work in a war-affected region becomes entangled in a North Sea mystery when a vanished package, a wrecked ship, and a submarine labeled U-13 lead to shipwreck, rescue, and espionage threats. The narrative follows their searched passage into neutral territory, subsequent maritime dangers, mistaken identities, and strange craft sightings as the boys apply scouting skills, courage, and quick thinking. Encounters with allies and enemies alike gradually reveal the truth behind the submarine’s appearances while testing the lads’ resourcefulness and loyalty in a sequence of suspenseful, action-driven episodes.
