Barnaby Crisp is back, and the stakes have never been higher in the glittering heart of Las Vegas!

Following their baffling investigation in The Case of the Caffeinated Capuchin, eccentric detective Barnaby Crisp and his pragmatic partner Maya Sharma are called to the exclusive Sapphire Slipper Casino, where impossible thefts are occurring with clockwork precision. Million-dollar watches and priceless art vanish from secure suites, leaving behind only the baffling signature of an exact seven-minute timeframe.

While Maya deciphers schematics and security logs, Barnaby deploys his unique detection grid: a network of strategically placed rubber ducks designed to resonate with quantum patterns others miss. As they chase the "ghost path" vulnerability, they uncover a conspiracy far more complex than simple theft—one involving deliberately engineered security flaws, ambitious corporate rivals, and the potential compromise of next-generation technology.

Can Barnaby's ducks and Maya's logic expose the truth before time runs out? In this thrilling sequel, the unconventional duo must navigate a world of illusion and high-tech deception, where the biggest gamble is trusting that the most absurd methods might be the only way to win.
