The third case in the compelling Boy Sherlock Holmes series is full of as many twists and turns as the backstreets of Victorian London.

When a wealthy young girl vanishes as if by magic in Hyde Park, Sherlock is once again driven to prove himself. In a heart-stopping race against time, an innocent boy's survival depends on Sherlock's ability to solve the mysterious puzzle of the Vanishing Girl. As complex as the maze that protects the missing girl's hiding place, this case takes Sherlock racing to the countryside, the coast, and into the lair of a menagerie of exotic, dangerous creatures.

Haunted by memories of his shattered family, goaded by his enemies, driven to heal the fragile relationship between him and the beautiful Irene Doyle, Sherlock makes an almost fatal mistake. In the end, his brilliant powers of deduction and the steadfast eccentric Sigerson Bell save the day. Soon, very soon, the world will come to know him as the master detective of all time.
