–Mike McSwiggin, Baker Street Journal

“By far my favourite [of volumes XXXI – XXXIII] was Mark Wardecker’s telling of the truth regarding the Politician, the Lighthouse and the Trained Cormorant, which was incredibly canonical in feel and plot.”
–Paul Thomas Miller, Sherlock Holmes Journal



My Sherlock Holmes story, “The Adventure of the Second Round”, has been anthologized in Wildside Press’ Sherlock Holmes Megapack which can be purchased from Amazon and iTunes. The story originally appeared in Sherlock Holmes Mystery Magazine 5.

Another one of my Sherlock Holmes pastiches, “The Adventure of the Docklands Apparition”, has been published in issue 10 of Marvin Kaye’s Sherlock Holmes Mystery Magazine.

The Dragnet Solar Pons, an edition of August Derleth’s early Solar Pons stories that I annotated and wrote the introduction for, is now available (ordering instructions). These Sherlock Holmes pastiches were written for various pulp magazines in the late 1920’s and early 1930’s, and the annotations address the differences between these early versions of the stories and later anthologized versions published by Arkham House and Pinnacle, as well as parallels to the original Sherlock Holmes stories.
“An important collection.”
