Many thanks to the following:

Jeremy Lassen and Jason Williams at Night Shade Books, for letting me edit all these anthologies and for doing such a kick-ass job publishing them. Also, to Ross Lockhart at Night Shade for all that he does behind-the-scenes, and to Marty Halpern for catching all my tyops.

David Palumbo, for the Holmesarific cover.

Gordon Van Gelder, the Dr. Joseph Bell to my Sherlock Holmes (i.e., the model upon which my career is based). Of course, unlike Holmes, I am not a fictional character, or so the voices tell me.

My agent Jenny Rappaport, the Mrs Hudson of my literary estate.

David Barr Kirtley for serving as my Watson during the assembly of this volume. All the clever things in the header notes are all his work. Anything lame you came across is mine.

Rebecca McNulty, for her various and valuable interning assistance—reading, scanning, transcribing, proofing, doing most of the work but getting none of the credit as all good interns do.

My mom, for the usual reasons.

All of the other kindly folks who assisted me in some way during the editorial process: Charles Ardai, Jack Byrne, Frances Collin, Andy Cox, Ellen Datlow, Jake Elwell, Jennifer Escott, Emily Giglierano, Lina M. Granada, Merrilee Heifetz, Patricia Hoch, Mary Robinette Kowal, Dorothy Lumley, Donald Maass, Andrew Marszal, Linda Moorcock, Barbara and Christopher Roden, Betty Russo, Charles Schlessiger, Steven Silver, J. L. Stermer, Craig Tenney, everyone who dropped suggestions into my Holmes fiction database, and to everyone else who helped out in some way that I neglected to mention (and to you folks, I apologize!).

The NYC Geek Posse–consisting of Robert Bland, Christopher M. Cevasco, Douglas E. Cohen, Jordan Hamessley, Andrea Kail, and Matt London (plus Dave Kirtley, who I mentioned above, and the NYCGP Auxiliary)–for giving me an excuse to come out of my editorial cave once in a while.

The readers and reviewers who loved my other anthologies, making it possible for me to do more.

And last, but certainly not least: a big thanks to all of the authors who appear in this anthology.
