I like Sherlock Holmes as a character and know just enough about him to enjoy books like this one, without worrying about any fictional liberties taken with his author Arthur Conan Doyle. Chapters alternate between two time periods (1900 and present day) and two mysteries. The link involves a missing diary of Arthur Conan Doyle. I think book club members would enjoy the book. Discussion topics - looking beyond the engaging concurrent mysteries - should not be a problem with some forethought.

Toggling between present day and Arthur Conan Doyle's life (late 1800s/early 1900s) and tying the two together in typical Sherlock Holmes style, Graham does a good good of keeping the reader engaged, entertained and thinking. It was an enjoyable and easy flowing read.
