Inseparable friends, Tif the bald and Tondu, the bearded one, solve mysteries in a series midway between crime and fantasy. They find themselves face to face with a giant robot built in the Middle Ages, they have to fight an invisible gorilla with a human brain, they must find out how security people are killed with a remote beam, or prevent the burglary of the Louvre. They always find Mr. Choc, the international bandit dressed in tuxedo and medieval helmet on their way. A series of adventures with a gripping atmosphere and an irresistible charm. By Will, Dineur, Rosy, Desberg, Lapiére and Sikorski.
