Eleven-year-old Jack Putnam and his eight-year-old brother Benny are being dragged against their will on a summer-long vacation with their family. And not to somewhere cool like Disney World, but to a little port town in Maine named Chowder Bay, far away from anyplace fun. But what promises to be a very bleak summer quickly becomes a series of exciting adventures in one of the most mysterious places on earth! This third volume has the boys investigating the mysterious death of Dr. True, a 19th century inhabitant of Chowder Bay who is most famous for 'Dr. True's Wonderful Elixir'. Was the town's famed hero, Captain Holister, involved? As with everything else in Chowder Bay, not everything is as it appears.
