Conan pastiche is always a sticky subject. There are REH purists that will not read them on principle, and there are Conan fanatics that make little distinction. I fall somewhere in between.
Early to late 80’s, I fell deep into Conan fandom; first, it was my discovery of the Marvel Conan comics, particularly The Savage Sword of Conan, second and of great lasting power, I watched the 1982 Conan the Barbarian movie. In my mind, anything Conan was at least vaguely connected to my love of Dungeons & Dragons, which made it Metal. Metal was of prime importance.
During the 80’s and into the early 90’s, I read a steady diet of Tor Conan novels by various authors. This is the first I’ve read in decades, and did so after cleaning my garage and finding a nearly forgotten box of Tor Conan’s. Many read before, some not. To the best of memory, I had not read this one before. Who can say? I know for a fact I’ve read all of the Robert Jordan Tor Conan’s, but for the life of me could not describe the plot of any. The Tor Conan’s are ephemeral. They take little time to read, are often fun, but have no lasting power.
In my 30’s, I became a hard nosed REH fan. Having read a large percentage of his true, unedited, works. I prefer the pure REH to pastiche; however, I still read the pastiche of de Camp and Carter, but mostly through the lens of Roy Thomas and his band of, my favorite, Conan artists. Leaving the comics equation out of it, I would call the de Camp/Carter Conan: de Conanter.
I also enjoy reading the the S&S REH imitation works of John Jakes, Gardner F. Fox and L Carter. Heroes with names like Brak, Kyrik and Thongor. Call these: Clonans, Clones of Conan.
Perhaps a third category is needed: Tornan’s, Tor Conan?
The Tor Conan’s feature REH’s creation, and sometimes even resemble the Cimmerian, but they never get it exactly right. Take the novel in review here: in this book, Conan trusts and depends a bit too much on Sorcery. He allows himself to be bullied into a plot that he wishes no part of. Conan is more of a thinker than many give him credit for, but the Conan of John Maddox Roberts is a bit too cautious. JMR makes a distinction between sorcerers and priests. In the S&S works of Howard, no difference was ever made, they were interchangeable and often one in the same. Also, JMR develops “schools” of magic that seem not very Hyborian age-ish, at least REH never developed magic this way. The magic of JMR is a bit too flashy for my taste. I prefer subtle and mysterious.
As an adventure story, Conan and The Manhunters is not terrible. It clips along at a steady pace. It gives some memorable characters. At its heart, it is a heist story wrapped up in a chase plot, flavored with revenge. It even has some nice horror elements within the temple of Ahriman, but less Lovecraft and more splatter-punk. Like all good, or at least average, heist novels it is full of unseen complications and double crosses.
It also has its weaknesses. The Manhunters of the title are a professional group of bounty hunters hired to bring Conan and his misfit pack of brigands to justice. Their leader is a badass Aquilonian promised to possibly be Conan’s equal in battle. It’s hinted at, their inevitable confrontation is built up, built up and summarily handled in a page and a half.
Also, and this is a gripe of mine, the EVIL priests of the Destroyer and pure EVIL god, who is so EVIL even Set and his priesthood said “this Dude has to go”; the priesthood is EVIL and wants to bring their god into the realm of men so he can devour it all and set them up as rulers of....wait? Of what? This bad ass dude is going to devour it all, so what are you going to be kings of? Did this subject never come up at your EVIL tea-party social hours?
If it wasn’t disguised as a Conan book, and was instead a Clonan, I would have enjoyed it more.
