The ultimate - and official - guide to the BBC hit series Sherlock

This book is my humble attempt to shine a light on the work of the best and wisest I have ever known. He has, I think it is safe to say, elevated the science of detection into an art form. Having been at his side during some of his most remarkable cases, it has fallen to me to bring his achievements to the attention of the wider public. He is, quite simply, the Mozart of criminal investigation.

I would say more, but I am flattered and delighted to say that Sherlock Holmes himself has agreed to write a piece for the cover. John Watson

Don't buy this book. The author has transformed what should have been a series of lectures into a gross and tasteless entertainment. The science of deduction is a branch of human achievement requiring serious analysis and yet here I find it lavishly illustrated, disfigured with humour and infested with gossip.

Apparently, this kind of sensationalism is required to engage the interest of the reading public, but it is rather like working an office romance into a paper on quantum physics. Only an idiot would be impressed. Help yourself. Sherlock Holmes
