Query: Warning! Sherlock Holmes Fans: Don't Read

Self-serving destruction of a classic character, the story is engaging through its pages, and incorporates many of the snippits and characterizations of Doyle's stories... but without the greatness that has made Doyle's characters live and be loved for so long.The ending is an atrocity... and so far-fetched that I, too, was looking for the double-twist ending - which did not arrive. This book is an injustice to a fine writer, Doyle... and a fine character... and to a large group of fans of all the Holmes stories - Doyle-created or otherwise.This is not a book for true Sherlock Holmes fans.
