From The Perry Mason TV Show Book (Revised)
Perry is all set to go deep-sea fishing with Paul aboard the Viajero II, a fishing boat out of San Diego owned by Perry’s friend Scot Cahill. But when Cahill’s regular customer has the boat for the weekend, Perry has to charter another boat. Later, Perry gets a ship-to-shore phone call from Scot. The Coast Guard, acting on a tip, boarded the Viajero II looking for gold stolen from the Alchemy Mine. They found some bullion-and a dead man, Karl Magovern. Later, the autopsy reveals the stiff was killed with a fatal dose of digitalis. Worse, the police charge Scot with the murder, thinking he and the murdered man were partners in stealing the gold bullion.
