I mondi impossibili di Sherlock Holmes

Martin, Diana and Java are in London to participate in an evening in honor of Sherlock Holmes, during which the rich and eccentric Trevor Gould will present an unpublished manuscript of an adventure of the famous detective. But Gould is killed and the manuscript disappears. Meanwhile, in a secret place near the city, someone is using children as guinea pigs for dark experiments. One of the children, however, manages to escape and asks the Detective of the Impossible for help! The murder of Sherlockian expert Trevor Gould was committed by the same people who are conducting secret experiments on some kidnapped children: the link between the two crimes is revealed thanks to Gould's manuscript, which turns out to be the work of Sherlock Holmes himself!
