If you've always fancied yourself a bit of a Sherlock Holmes, there's no better way to test yourself than against these ingenious puzzles.

In this intriguing book, Stewart Ross presents 25 new Sherlock Holmes cases and challenges you to pit your powers of deduction against those of the Great Detective. Full of the atmosphere and ambience of 221b Baker Street, you'll feel like you've stepped back into the pages of Arthur Conan Doyle . except, this time, with the chance to prove you're a match for the super sleuth.

Each case provides all the evidence you'll need to crack it, provided you're sharp enough to pick up on all the clues, with challenges from codebreaking to lateral thinking, memory to logic . and of course, how Sherlock came up with the solutions can be found at the back of the book in case you're feeling more like Watson than Holmes.

The detective managed to solve 24 out of the 25 cases in this book - perhaps you can go one better.
