The G-Man's Son at Porpoise Island

All Stanley Sandborn wants is a summer sailing trip with his friend John, far from the shadow of his father's FBI career. But the moment their sloop Water Witch strikes something submerged in the dark water near Porpoise Island, the vacation takes a deadly turn. Strange lights flicker across the bay. Mysterious speedboats prowl the coastline. And the enigmatic Mr. Nevens, with his too-friendly smile and evasive answers, is clearly hiding something far more dangerous than a failed camping trip. The sons of G-Men don't get to sit on the sidelines when criminals are at work. Stanley and John must use their wits, their courage, and their friendship to survive an underworld conspiracy that grows more perilous by the hour. This 1937 adventure captures the raw excitement of two boys who bite off more than they can chew and must chew their way out.
