The Death of Cardinal Tosca: An Untold Adventure of Sherlock Holmes (The Dispatch Box of John H. Watson, MD) (Volume 3)
"Ashton seems to have a knack for hitting a very convincingly canonical mark, making his stories some of the most consistently plausible I've found.The Death of Cardinal Toscamay well be my favorite of those stories so far. The atmosphere feels warmly familiar, the mystery plausible, yet delightfully recherché, the historical aspects carefully researched and the canonical details thoughtfully upheld. If you're a Sherlock Holmes fan who's read through the Canon and are aching for more, this is the book for you!"
