Carlow related that he had been kidnapped in Paris by men who had offered to buy his invention and flown him to the island in a seaplane. Actually they wanted to prevent him from clearing himself or revealing what he had discovered about Vaxilis’ true character.
Tom made no comment. Instead, he hastily inspected the house. Although it was purposely plain and unimposing from the outside, it was comfortably furnished and well stocked with provisions. The Delian Apollo and the stolen paintings were stored in a bedroom with drawn draperies over them. The gold bullion, also covered, had been stacked along one wall.
Noticing a powerful radio set and a phone, Tom asked, “What’s the phone for?”
“It communicates with the sub in the harbor, Bud replied. “And that switch on the wall controls the whirlpool machine.”
