While Titan Books prepares SHERLOCK HOLMES VS. CTHULHU: THE ADVENTURE OF THE DEADLY DIMENSIONS for July 11, 2017 publication, I’m putting the finishing touches on the second novel in the series, THE ADVENTURE OF THE NEURAL PSYCHOSES.

As soon as I finish editing and polishing the second novel, I’ll write a couple of short stories, then turn my attention to the third novel in the SHERLOCK HOLMES series.

It’ll be interesting to see the book cover for the second novel. Titan revised my book cover at the last minute to what you see on this page. Notice (this is a teaser) the machine, the eye, the magnifying lens, and the tentacles.

FIRST in a new series of Sherlock Holmes thrillers! 

All novels will be available at, Barnes and Noble online and book stores, as well as other fine shops

A series of grisly murders rocks London. At each location, only a jumble of bones remains, along with a bizarre bone sphere covered in arcane symbols. The son of the latest victim seeks the help of Sherlock Holmes and Dr. John Watson, who discover a common thread that ties together the murders–and the persons responsible.

Bizarre geometries–based on ancient schematics–point to members of a secluded cult. These men and women build strange constructs that will enable other-worldly creatures to enter our dimension, seeking sustenance. As their power grows, even Moriarty fears that his empire is at risk—to the point that he seeks an unholy alliance with his eternal foe.

Holmes_forwebADVANCE PRAISE 

THE ADVENTURE OF THE DEADLY DIMENSIONS is a wild, exciting and thoroughly satisfying collision of otherworldly horror and deductive reasoning. So much fun!”
–Jonathan Maberry, New York Times bestselling author of V-WARS and PREDATOR ONE

“An irresistible eldritch mystery! Baker Street and the Great Old Ones are made for each other.”
–Christopher Golden, New York Times bestselling author of Snowblind and Aarat

THE ADVENTURE OF THE DEADLY DIMENSIONS held me spellbound and kept me guessing…until 3 AM on a work day! The Great Detective has met his literary match, and ‘The Woman’ is author Lois H. Gresh. More!”
–Nancy Holder, New York Times bestselling author, the WICKED Saga

“The Great Detective confronts the Unnameable in Lois Gresh’s latest—grand fun!”
–Leslie Klinger, World Fantasy Award winning editor of The New Annotated Sherlock Holmes and The Annotated H.P. Lovecraft

“The name Lois H. Gresh is as much advertising as her work needs. However, it is my privilege to recommend her latest tour-de-force. Just how the literary establishment missed engineering a dream collaboration between H.P Lovecraft and Arthur Conan Doyle before now is a mystery; but if it was waiting for Lois H. Gresh to do the thing justice, this one is all the justification necessary.”
–Loren D. Estleman, Edgar Award-Winning author

“Lois H, Gresh blends Sherlock Holmes and and the eldritch flavors of H.P. Lovecraft together brilliantly. Victorian nightmares and a properly twisted mystery make THE ADVENTURE OF THE DEADLY DIMENSIONS a must read for fans of Sir Arthur Conan Doyle’s legendary sleuth.”
–James A. Moore, author of Seven Forges and The Blasted Lands


Malice Domestic – this weekend!

I’ll be at MALICE DOMESTIC (Bethesda, MD) this weekend. My panel is SHERLOCK LIVES! (Sunday, May 1, 10-11 am) with John Betancourt (moderator), Lois H. Gresh, Laurie R. King, Bonnie MacBird, and Michael Robertson. I’m psyched to be on a Holmes panel with Laurie R. King – wow! We also have a signing on Sunday at 11 am, directly following the panel.


Holmes_forweb Earlier this week, I finished writing the draft of SHERLOCK HOLMES: THE ADVENTURE OF THE DEADLY DIMENSIONS for Titan Books. I wrote the novel in 6 months. In manuscript form, it’s 511 pages and 104,000 words. 

I now must edit the manuscript before turning it into my “real” editor at Titan. 

Most of my friends don’t understand what this means. 

The term, editing, does not mean a mere checking of spelling and grammar. Sure, if I see proofreading-type errors, I’ll fix them. But what I’m looking for during my editing phase are bigger problems: inconsistencies, redundancies, stilted dialogue, weakening of tone or voice, balance of style, coherent logic, character development, lack of tension, wrapping up of any loose ends, overused words or phrases, BALANCE (worth repeating).

SH_webHow do I explain what I do to my friends, who are not writers? First of all, most of them never ask me about the writing process. They assume that the writer bangs something out, voila, it’s perfect and ready to go, and magically, a publisher comes along and prints it. Anyone can be a writer: anyone. They assume that the publishing house’s editor does all the editing – !

Ask any professional writer if it’s wise to submit a manuscript that requires a huge amount of editing by the “real” editor, and here’s what he or she will tell you: never do it! 

SHERLOCK HOLMES: THE ADVENTURE OF THE DEADLY DIMENSIONS is my 30th book, and I’ve also published 65+ stories. In addition, I’ve written 200+ technical manuals and 100+ medical and scientific newsletters, as well as 50+ science articles. I’ve edited two short story anthologies in the past couple of years. For 20 years, I was a manager of technical documentation, training, and systems analysis. 

This doesn’t make me a god of writing or editing. It does mean that I have a bit of experience. 

Trust me, you do not want to submit a manuscript to a professional editor unless you’ve edited it yourself. 

Holmes1With SHERLOCK HOLMES, I’m reviewing my manuscript to make sure that my Holmes and Watson (and various other characters) conform to Arthur Conan Doyle’s canon. I must make sure that my scientific speculation is true to the time period in which I write. I must add something new and vigorous to the canon without contradicting it. 

Given that SHERLOCK HOLMES: THE ADVENTURE OF THE DEADLY DIMENSIONS has a Lovecraftian/weird twist, I must make sure that my Holmes remains true to character while dealing with something extremely odd. 

I typically ground my tales in science. Even if I don’t divulge the scientific (or otherwise factual) underpinnings, a story must make sense to me, or I can’t write it. Sometimes, I do go off on flights of fancy, and venture into the purely supernatural/metaphysical realm; but this is rare. I’m typically jumping off from fact into fiction. 

So in my first SHERLOCK HOLMES novel, you might think I’m in a purely supernatural/metaphysical realm, but I’m not. And my Holmes knows that I’m grounded somewhere in science, too. 

SHERLOCK HOLMES: THE ADVENTURE OF THE DEADLY DIMENSIONS is the first novel in a trilogy that I’m writing for Titan Books. While my editor and I hash through book #1, I’ll be researching, outlining, and writing book #2. Busy times ahead! 

In all honesty, I’ve never had this much fun. I’m completely obsessed with SHERLOCK HOLMES, and nothing makes me happier than writing these novels.

It reminds me of the time I got to watch STAR TREK as my “day job.” Or when I read 500 comic books as my “day job.”

Writers work like dogs, but we do have our fun.


Supernatural Crime Thrillers – 3 Novels in a New Series!

THRILLING NEWS! I just received a contract from Titan Books for the first 3 supernatural crime thrillers in an original series.

I’m extremely thankful to Steve Saffel for believing in me. Huge thanks also go to Jonathan Maberry, Christopher Golden, James A. Moore, Nancy Holder, Leslie S. Klinger, Loren D. Estleman, and S.T. Joshi.

I’ve spent the past 4 weeks writing an extremely detailed outline of Novel #1. Now I’m filling in details for Novels #2 and #3. I’ve also been buried in research, which is one aspect of writing that I truly love. Research is a great excuse to read a lot of books and learn all sorts of cool things!
