Thunder, Beach, a tale of wreck salvaging set in Florida, was Mr. Watkins' last mystery adventure (see also Venture West, Crocodile Crew etc.). This one takes a turn north again as young Sandy Rudd, through a misconceived wrong, gets stuck for the winter in a small Connecticut sea town and becomes instrumental in starting a dredging job to clear its harbor of mud. Accused of wrecking Bart, a local boy's boat, Sandy must go to work and to the local high school while his father is off trying to start a news agency. ""In bad"" from the start, Sandy continues to take raps and get into undeserved jams until tough old Mahogany Slocum sees a spark of virtue in the boy and gives him a job at his boat yard. The work puts him into close contact with Bart, whom Sandy knows to have let his boat go adrift in the first place, though he knows too, he was careless in trying to rescue it. The climax, a tense moment while salvaging a valuable relic from an old ship, squares off their differences, while their discovery creates a new community interest in dredging the bad harbour.
