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.

Should have stopped at two

Not as good as the first two books, but makes for good sleeping white noise as Dennis Kleinman has a soothing voice.

a little bit silly, thoroughly good fun

while this series does not really tap into the horror of other cosmic properties, you get the feeling that it wasn't going for that.
I thoroughly enjoyed the slightly silly romp from beginning to end.

Shokushu Holmes

Highly-entertaining conclusion to James Lovegrove's Holmes / Cthulhu mash-up trilogy. Here the narrative sets course through a tinderbox pre-WW1 Europe before taking to the high seas and the non-Euclidean geometry of dread R'lyeh, all in a fast-paced attempt to thwart the sinister machinations of a now deific Professor Moriarty. Holmes and Lovecraft pastiches are ten-a-penny but this is hugely enjoyable and well-written; the addition of tentacular cosmic horror galvanising the Great Detective's game. A talented writer, Lovegrove nods to both Doyle and Lovecraft's authorial voices, yet this most resembles the rip-roaring Boys Own style of John Buchan, which, intentional or not, works surprisingly well in balancing both elements together. The narration is excellent, too.

It wasn’t quite Sherlock Holmes

The trilogy didn’t quite capture the spirit for me. I think it was the terminology used throughout. And the final chapter with the author losing his mind was nonsensical. Kinda ruined what wasn’t amazing to start with.
