Sherlock Holmes and the Disappearing Diamond

Sherlock Holmes is on the case!

John Watson has barely settled into his new school, Baker Street Academy, when his teacher announces a trip to one of London's top museums, home to the Alpine Star, the world's most famous jewel.

But the gem has been stolen! The police are soon on the trail and the whole of the country is talking about the crime.

When police catch the thief along with the stolen gem, it seems the case is closed. But Sherlock Holmes has other ideas. With John and Martha at his side, can he uncover the mystery behind this extraordinary gem?

Told through Watson's blog, detective notes, school assignments, media reports, and energetic comic-strip illustrations, this introduction to Arthur Conan Doyle's classic characters will have every young super-sleuth hooked!
