SECOND BOOK in a new series of Sherlock Holmes thrillers! 

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

Amelia Scarcliffe’s monstrous brood, harbingers of Cthulhu, will soon spawn. Her songs spell insanity, death…and illimitable wealth. And Moriarty will do anything to get his hands on gold, even if it means tearing down the walls between this world and a realm of horrors.

Meanwhile, after Sherlock Holmes’s last tangle with the Order of Dagon, horrifying monsters haunt the Thames, and madness stalks the streets of Whitechapel. Gang war between Moriarty’s thugs and the powerful cult can only bring more terror–unless Holmes and Dr. Watson can prevent it. But can they find the cause of the neural psychoses before Watson himself succumbs?

Praise for the Sherlock Holmes vs. Cthulhu series

“If you like your detective stories with a dash of the occult, Sherlock Holmes vs. Cthulhu: The Adventure of the Neural Psychoses is for you. Holmes vs. Cthulhu, what more could you want?”
– Horror Channel UK

“An excellent mash up of Doyle and Lovecraft that I can’t help but applaud. Gresh masters both [Holmes and Lovecraft] perfectly and exceedingly, I was completely blown away! The characters of Holmes and Watson were perfect renderings that even Doyle would approve of. The plot line was amazing, it wasn’t too OTT making it silly or ridiculous, it was just the right amount of terrifying meets bizarre and worked wonderfully. A trilogy that any fans of Sherlock, Lovecraft, SFF or historical fantasy would love.”
– Tygpress Book Reviews

“The author yet again nailed Holmes and Watson’s personalities… I cannot wait for the final book in this series.”
– Terror Tree UK

“Lois is leading the charge in revitalising a rich and interesting character with new challenges”
— Always Trust in Books

“A rollicking read for its enjoyable literary mash-up as well as its genuinely great rendering of both Holmes and Watson”

“A wild, exciting and thoroughly satisfying collision of otherworldly horror an deductive reasoning.”
— Jonathan Maberry, New York Times Bestselling Author

“Held me spellbound…more!”
— Nancy Holder, New York Times Bestselling Author

“An irresistible eldritch mystery.”
— Christopher Golden, New York Times Bestselling Author

“Grand fun!”

FIRST in a new series of Sherlock Holmes thrillers! 

All novels are 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

An unmissable collision of two of the finest Victorian treasures. No stranger to the Cthulhu mythos, Gresh’s Lovecraftian writings have appeared in many anthologies, so the subject matter is in safe hands, leaving the addition of Doyle’s master detective the icing on an already appetising cake.”
   —This is Horror,

“Gresh is an excellent plotter as she weaves an engaging mystery that builds from typical Holmesian fare into pure Lovecraftian horror. Along the way, Gresh raids the toybox of both Doyle and Lovecraft and employs both of their tropes and commonly found story elements, so fans of both authors’ styles will find much to love about this novel. A rollicking read…genuinely great rendering of both Holmes and Watson, in particular the latter. The good news is that this is only the first of a planned trilogy, so we can look forward to even more ‘Cthulhu meets Conan Doyle’ goodness in future.”
Christian Bone, Starburst,

“You would think that no-one could recreate Holmes a century later than Conan Doyle did, but Gresh has managed to get both Holmes and his ‘assistant’ Watson pegged…In this well-written novel Gresh closely follows the Holmes conventions, whilst stepping outside of the day to day and entering the fringes of the supernatural… a fast moving and strange book.”

Black Static magazine review


Cult of the Dead: The supernatural aspects are fascinating and have a novelty to them that is missing from most material in this vein, while playing counterpoint to the outré elements is an awareness of human suffering and human greed, things that negatively impact on each other. And while it may not be entirely agreeable to non-Incans, there is a rightness to the story’s end that makes the reader want to cheer.

Dreams of Death: It’s a fascinating tale, one in which even though the protagonist is doomed to fail we cannot help but feel for him and share in the triumphalism of his end.

Necrotic Cove: an engaging study of resentment and what it can do, how we use each other even when we don’t intend to do so

Old Enough to Drink: remarkable and disturbing imagery

Death Doll: Beautifully written, ‘Death Doll’ gives us an original take on the Grim Reaper, with a baby spared only to cause complications further down the line, the story arguing for the rightness of death in its time. I loved the ideas being put forth, and the first person off kilter narration by Death.

Let Me Make You Suffer: a fascinating brew of science, sex, and horror.

The Lagoon of Insane Plants: Endless invention and a constant playing with the tropes of this sub genre. Enjoyable and provocative.

Debutante Ball: a strange and savage story, one in which the feminism bleeds from the text.

Snip My Suckers: the narrative reading like a version of Little Shop of Horrors on speed, I loved every blackly comedic moment of it.

PsychoMildew Love: There’s a gonzo quality to ‘Psychomildew Love’, the story of witch Cora and how she realises her passion for neighbour Warren by turning him into an ant eater, and while it should be absurd, Gresh’s prose and her willingness to go the extra bit further into madcap invention result in a story that I thoroughly enjoyed

Algorithms and Nasal Structures: It’s full of ideas and has about it a feel of just desserts served for those most deserving. I liked Amy, and Frank was believable, but not especially likable, which worked fine for the story. And the thing with the scents added an element of novelty.

Digital Pistil: We get another manic story with ‘Digital Pistil’, the tale of two digital flowers in love, which is as crazy as it sounds, but done with considerable panache and conviction, so that their affair plays out like the mirror image of so many unhappy human relationships, with the cat High and Mighty performing a catalytic role.

Mandelbrot Moldrot: charming and inventive…the reader can’t help but be entertained

Cult of the Dead and Other Weird and Lovecraftian Tales by Lois H Gresh contains many good things in the Lovecraftian tradition. The stories are forceful and visceral in their execution, and varied in their settings—most of which make Innsmouth seem like the most exclusive garden suburb continually bathed in sunshine. For example, the vivid title story is set in the catacombs of a monastery in Lima, where an illegal excavator discovers that the past is not as dead as it seems (or should be) and the current order is revealed for the transitory situation in reality it always was.”
– John Howard, Wormwood 27 magazine review

“Gresh’s elegant and mellifluous prose, the imaginative power of her weird conceptions, and her skill in leading the reader step by step to a terrifying denouement make every one of her tales a well-crafted jewel of weird fiction.
— S.T. Joshi
