Alexander and Norma Gold are asked to help prove their friend Pearl's niece's fiance innocent after he was found bent over his employer's dying body with the bloody knife in his hands. The victim is Roger Talbott, one of America's most famous Architects, and the crime scene is his studio floor atop his brownstone mansion, which was as securely guarded as a fortress by various devices. With the date of the trial getting closer, Alexander is forced to solve this puzzle quickly, which isn't exactly the most appropriate activity while recovering from a heart attack...
Alexander and Norma are invited by billionaire Max Baron to join him and his family during a performance of the Boguslav Ballet. Baron suspects someone "reading his mind", or simply put the leakage of information, and the request for Alexander to solve that issue is the original purpose for the invitation, However Alec and Norma are soon hired for something entirely different, when Viktor Boguslav is stabbed in the theatre box adjoining the Barons and the Golds, only parted by a curtain and with Baron's son Jeffrey as Boguslav's assistant sleeping right behind his employer in the cloakroom in front of a locked door! The Golds have a mere deadline of less than three days to prove someone else than Jeffrey could do it.
