Sherlock Holmes
“SHERLOCK HOLMES AND THE MYSTERY OF THE DEVIL’S EYE”
Set in modern day London, Sherlock Holmes has been called in by Scotland Yard to investigate the theft of the world’s largest ruby, the Devil’s Eye. Stolen from Harrods, the police have nothing to go on except a few mathematical clues.
Your students’ challenge is to solve the clues to help Holmes and Watson work out where they must go next.
Last Autumn Longman ran this popular competition for KS4 Maths classes. We’ve now gathered all six episodes of the story into this one booklet which is entriely free for you to download. Best of all, the resource is closely linked to the GCSE curriculum. Each question carries a GCSE grade and an AO2/AO3 label – perfect for testing the new 2010 specification. For a quick preview, you can download the Prologue.
Have fun, and stay safe at night!

I would like to take part in the competition with my students starting today.
Hi Richard – glad to hear you want to take part!
Episode 5 is being posted to the blog later today. It will be sent straight to the inbox of all subscribers. Alternatively, you can just look on the blog after lunch.
The post will tell you everything you need to know: how to enter (very simple), the prize (very generous), and the maths activity itself (very fun).
You don’t need to read the earlier episodes to take part, but you’ll find they flesh out the story.
Let us know if any other questions?
