Cast & Crew
In a New York City skyscraper, amateur detective Terence "Slip" Mahoney and his pal Sach are working as an office cleaning crew when a letter is delivered to Terence Mahoney, Esquire, informing him of an inheritance from his uncle of a Long Island cliffhouse called Mahoney Manor. Slip assumes the letter was meant for him and goes with his friends to the manor, unaware that the real Terence Mahoney, Esquire and his daughter Teresa are awaiting the arrival of the letter. As Slip approaches the front door to the manor, a gunshot goes off. Undaunted, Slip confronts the caretaker, Digger, who is really the henchman for a foreign smuggler and diamond thief named Count Boris Petrov, who is using the manor as his headquarters. Digger welcomes the boys and shows them to their rooms, after which Petrov sets about trying to scare them into leaving by peering menacingly through their windows. The next morning, the boys follow "Ajax," Digger's Great Dane guard dog, through a secret passageway in the fireplace, and are caught by Petrov and locked up in a basement room. Meanwhile, Mahoney, badly in need of a rest cure, arrives with Teresa, and Digger gives them the bedrooms upstairs. In the night, they, too, are frightened by Petrov's face at their windows. Next, the boys' reporter friend, Gabe, arrives and discovers the real Mahoney in bed. He then notices a series of light flashes sending a code across the water, and discovers Digger and a sea captain accompanying a foreign woman into a cave that leads from the shore to the manor. Petrov immediately demands the precious Monrovian diamond from the woman, who is Sandra Hasso, and she reluctantly removes it from her hair. Gabe reenters the manor and, hearing Sach screaming in a panic, frees the boys. Gabe tells them that Mahoney is the boss of the smugglers, but when they awaken him, he proves he is the rightful heir to the house. With Mahoney and Gabe's help, the boys catch the criminals and retrieve the diamond. Mahoney, already tired of country living, then gives the manor to Slip.
