Publisher's Summary

The stunning novel from the New York Times best-selling author of The Age of Odin, in which the worlds of Arthur Conan Doyle and H.P. Lovecraft collide

It is the autumn of 1910, and for 15 long years, Sherlock Holmes and Dr. John Watson have battled R’lluhloig, the Hidden Mind that was once Professor James Moriarty. Europe is creeping inexorably towards war, and a more cosmic conflict is nearing its zenith, as in a single night all the most eminent members of the Diogenes Club die horribly, seemingly by their own hands. Holmes suspects it is the handiwork of a German spy working for R’lluhloig, but his search for vengeance costs an old friend his life. 

The companions retreat to Holmes’s farm on the Sussex Downs, and it is not long before a client comes calling. Three young women have disappeared from the nearby town of Newford, and the locals have no doubt who is responsible. For legend has it that strange amphibious creatures dwell in a city on the seabed, coming ashore every few centuries to take fresh captives. As Holmes and Watson seek out the terrifying interlopers, the scene is set for the final battle that will bring them face to face with the Sussex Sea-Devils, and perhaps with Cthulhu himself....

BRILLIANT! MY DEAR WATSON!

So! As a big fan of both Lovecraft & Sherlock I think the author has done a fantastic job of bringing them both together.
And as for the narrator.
Well done sir!
I think you have nailed it.
thank you both for a job well done.

so much fun

These stories have been so much fun. There is enough of the horror of Lovecraft to make it interesting, but not enough to give me nightmares. And all of the joys of Sherlock, without being too fantastical. This series was worth the time.

Boring and Slow

I am a lover of anything Sherlock Holmes. I've never read any Lovecraft, though. Perhaps that is the reason I found this book too far fetched and actually pretty boring. I guess I'm a Sherlock purist. Great narrator, though.

What a lame ending

Author gets a little carried away…. OK a lot carried away. Which was annoying. I’m embarrassed on his behalf.

Wonderful Sci-fi version of Sherlock Holmes

I hope Lovegrove writes more for this series. I cannot get over how much I’m enjoying them. They almost feel like the original Sherlock stories.

Ends the Trilogy on a High Note

Lovegrove finishes his trilogy about Sherlock Holmes and the Cthulhu mythos on a high note. I was pulled in right from the first chapter and kept turning pages (metaphorically) until the end. Almost immediately, the stakes are made clear when Mycroft Holmes and the entire Diageneses club are murdered to limit England’s ability to respond to the latest plot of Moriarity-turned-elder-God and Sherlock is consumed by a rage that seems to threaten his ability to be the great detective.

Yet the best part of all was the encounter with the Sussex Sea Devils themselves, with an obvious nod to Lovecraft’s Innsmouth. What follows was a sea voyage that was a bit drawn out, but then it was a very long voyage. And the conclusion over the fate of the cosmos was absolutely superbly Sherlock Holmes.

I think fans can quibble a bit with Lovegrove’s use of a certain elder god, but the overall impact of this story was completely satisfying.
