The Mammoth Book Of New Sherlock Holmes Adventures edited by Mike Ashley

(Used, paperback)
.
Singular, capital, wonderfully enjoyable, this is the biggest collection of new Sherlock Holmes stories published since Sir Arthur Conan Doyle laid down his pen - nearly 200,000 words of superb fiction featuring the Great Detective by masters of historical crime. Almost all the stories are specially written for the collection and the cases are presented in the order in which Holmes solved them. 
The result is a life of Sherlock Holmes, with a continuous narrative alongside the stories which identities the gaps in the canon and places the new and hitherto unrecorded cases in their correct sequence - plus there is an invaluable, complete Holmes chronology.
