The Boy Scouts on a Submarine

A young inventor develops a potent, nonlethal gas and believes its formula to be his proud breakthrough, but an attack leaves him unconscious and the only written formula missing. Family members, local detectives, and a band of resourceful Boy Scouts become entwined in the investigation; they encounter wounded companions, slain animals, and clues that suggest deliberate espionage. The narrative moves from household shock to organized pursuit as the youths and townspeople follow leads, confront suspects, and undertake daring field efforts to recover the formula and unmask those responsible.
