When Jack Hargreaves takes a job with Fingers Molloy, it doesn't quite go to plan. Fingers turns out to be a time-travelling burglar, with a host of ingenious devices supplied by the mysterious Mr Smith. And the things they're stealing are, frankly, odd. But Jack is in no position to pick and choose - for Jack has a secret too...
Sherlock Holmes is convinced that Fingers Molloy works for his nemesis, Professor Moriarty. Yet Inspector Lestrade won't take him seriously. How can the great detective prove he is right?
The further in Jack gets, the more serious - and mysterious - things seem. But breaking free and coming clean could land Jack in not just trouble, but danger...
