This book is one of fifty put out by Titan books in an extended line of Sherlock Holmes adventures by different authors. It contains a mystery within a mystery, and the pace is quite good. Davies has written five of the fifty books, and I plan to read more.

Holmes and Watson work very well together here, much like the later canon. This story has a twist; a solution half way through that turns out to be only half a solution. From this point forward, there are paragraph long asides from an omniscient perspective. This was a little jarring - most writers use Watson's perspective, as Doyle did. In this story, it worked, perhaps better than having those appear in the final summing up. 3½ stars.
