Sherlock Holmes will remain exactly the same character as he always has been in a new reincarnation of the great sleuth, author Anthony Horowitz has promised.
Horowitz, the children's author who wrote a series of novels about Alex Rider, a teenage spy, pledged to keep the character absolutely true to the original in Arthur Conan Doyle's original stories.
He told the BBC: "My Holmes is going to be exactly the Holmes of the novels without any new information on my part, I don't want to take any liberties with this great iconic figure."
The book, like the first of Conan Doyle's tales, is set in the 1890s but Horowitz said that writing in the 21st century he could "stray into areas Doyle couldn't have touched at his time".
Horowitz said: "What I think is different in my book is the nature of the crime, the world in which he gets involved.
"I do have a certain reservation about ... reinventions of old famous books which sometimes have a smack of desperation about them. Some work better than others and Holmes struck me as being right for this sort of reinvention."
Speaking about the opportunity to add to the canon of the world's most famous detective, he said: "I fell in love with the Sherlock Holmes stories when I was 16 and I've read them many times since.
"I simply couldn't resist this opportunity to write a brand new adventure for this iconic figure and my aim is to produce a first-rate mystery for a modern audience while remaining absolutely true to the spirit of the original."
