Billy's biggest wish is to turn a weird old wooden house into a wonderful sweet shop. But then he finds a giraffe, a pelly and a monkey living inside - they're the Ladderless Window Cleaners! They become best friends and when they meet the richest man in all England, there's a chance Billy's scrumptious-galumptious dream just might come true...

From the strange case of 'The Red-Headed League' to the extraordinary tale of 'The Engineer's Thumb', Sherlock Holmes and his assistant Dr Watson grapple with treachery, murder, and ingenious crimes of all kinds. But no case is too challening for the immortal detective's unique power of deduction.
