Becoming Sherlock – The Red Circle, the first instalment in the brand-new Becoming Sherlock trilogy by international bestseller Anthony Horowitz and Costa shortlistee Sarah J. Naughton, is out now.

Who is Sherlock Holmes?

We are 40 years into the future, and London is a city in decay. John Watson has returned from medical service in the war in Afghanistan and lives by himself in a run-down part of ​town. On his way home from work, he stumbles upon a beaten man in the street – unconscious and completely naked. His chances of survival are minimal.

The same evening, a passenger plane crashes in Richmond Park. There are several hundred victims, and Watson and the mysterious man are left to their own devices.

When the man wakes up the following day, he has no memory of who he is or where he came from but reveals excellent detection skills. This is the start of a mystery that unravels rapidly with one burning question at its core.

Can he solve the mystery of himself?
