Eminent Holmes scholar Klinger begins his latest volume with a sure-fire grabber: “A Checklist of Sherlockian Pornography,” which delivers exactly what it promises. The other contents include book reviews and essays on a wide variety of Holmes-related topics, many previously published in The Baker Street Journal, including the final piece, “On Annotating Sherlock Homes,” an account of his own emergence as a Sherlockian and his eventual compilation of a successor to W.S. Baring-Gould’s The Annotated Sherlock Holmes. He enumerates eight steps he followed in annotating the Canon, which he later applied to similar works on Dracula, Frankenstein, and the works of H.P. Lovecraft.
