The Fallible Fiend

Rate this book
The demon Zdim was happy with his philosophy on the Twelfth Plane, until he was conjured to Prime Plane to serve the human wizard Maldivius. There, to a logical fiend, men seemed wholly irrational. He was ordered to eat the first being to enter a sanctum, then beaten for devouring the wizard's apprentice, who sneaked through the doorway.

Prime Planers stole, lied, and fought each other in needless wars. Naturally, a totally logical demon couldn't understand them. And inevitably, Zdim made mistakes.

But when war came to the city of Ir, only Zdim could escape to seek rescue from wild soldiers and uncertain sorcerers. The role of savior should have gone to a hero out of the legends.

But there was only one Zdim — and he was fallible.

L Sprague De Camp will never go down in history as a literary great, but he's never written a boring novel either, and hardly ever one that wasn't damn good fun. The Fallible Fiend is one of his best standalone works, a satirical swashbuckler with a plane-walking demon as the main character. De Camp's on top form here; the plot flies along, the laughs come thick and fast. The characters, a rumbustious procession of rogues and grotesques, never fail to entertain. De Camp also has room to squeeze in a couple of astute Swiftian observations about the nature our species itself, though the book never falls into the trap of becoming a serious piece of work. It's frivolity all the way through.

A very fun,light read by LSdC! Our main protagonist, Zdim, is a demon from the 12th plane, who is 'drafted' to serve a human wizard Maldivius. It seems that the 12th plane has a shortage of iron and periodically, a demon is summoned by humans in return for some of that metal. Demons here are something like Klingons-- super rational-- and they must obey instructions by their human masters to the letter during their year of debt bondage. This combination leads to several humorous misunderstandings. Zdim is plunged into a vast array of trials and tribulations as his contract is sold over and over until finally war comes to the 'prime plane' with the invasion of a horde of cannibals. The only hope for the besieged city of Ir is for Zdim to act as an envoy to other peoples on the prime plane to help lift the siege of the (rather philosophical) cannibals. TFF is definitely tongue and check all the way and LSdC must of had a lot of fun writing it-- it was definitely a lot of fun to read. A perfect 'palate cleanser' from more serious reading. 3.5 stars rounding up.

An entertaining short novel of humorous fantasy that was just what I was looking for: light reading after a bad day. This is, to some degree, yard goods, but very nicely done. Here's a quote from near the end:

"By herself, Roska sar-Blixens is a grave, reserved lady, of great dignity and presence, even if she be ever changing her mind. Admiral Diodis is gruff, positive and forceful. Both are, one would say, as mature as one would ever expect of a human being. Yet, when together, they seem as full of careless laughter and foolish remarks as children...."

"It is simple," said Schnorri. "They are in love."

Fluff, but *good* fluff. Recommended for frivolous relaxation.

L. Sprague De Camp is famous for his numerous light fantasy novels. They are sort of the potato chips of fantasy lit, tasty but not particularly filling. This is one of his lesser works. It is told from the viewpoint of a "fiend" summoned to an Conan-esque world. The gimmick is that fiends aren't evil demons, but beings from a metal-poor alternate reality who are leased into temporary service in exchange for iron. This particular fiend is a philosopher in his own reality. The mild humor of the book revolves around his misunderstanding of the human culture and his literal-minded misinterpretations of simple commands.

I didn't actively dislike the book, but it isn't really worth the time to read it.

Hard to imagine this ever being a current fiction offering (in 1973.) It's an okay romp, but the language is self-indulgent, which means, unnecessarily tedious in emulating an Olde English style. I gave up on page seventy and read the ending, my guess is it lacks tension and has very little rising action. Once you've figured out the plot pattern it doesn't improve much. If I screwed up by DNfing this let me know.

Detta är en väldigt söt version av Gullivers resor: en filosofisk demon blir kallad att tjänstgöra ett år som kontraktstjänare. Här observerar han de märkliga "mjukskinnens" konstiga vanor. Det hela blir väldigt underhållande; framförallt eftersom demoner i denna värld talar och tänker med närmast matematisk logik och i och med att stackars Zdim (huvudpersonen) verkligen försöker göra rätt, utifrån de beskrivna parametrarna i talspråket.

Den är jätterolig. Läs den.

Stuff I Read – The Fallible Fiend by L Sprague de Camp Review

So kind of cheating here, because I was supposed to be reading Ursula K LeGuin’s Left Hand of Darkness next as part of my continuing efforts to read more female writers, but I got this book for Halloween and it’s very short and looked funny and so I’m sorry. In any event, this is (according to the internets) the third book in Camp’s series in Novaria, but really I don’t think it’s much of a proper “series,” as this is a stand alone book involving a demon summoned to the Prime Plane (read Novaria, your standard fantasy setting) and forced into the service of various wizards, conmen, and politicians, who invariable fail to utilize his talents to the fullest potential.

Zdim, the demon narrator, is a bit of a charming person…er, demon…whatever, because of his simplicity. He appeals to the reader’s own voice of reason. He is the comic foil of the setting, basically, operating under fairly strict rules, the biggest of them being that he takes commands literally, which ends up causing quite a bit of trouble throughout the book. As a comic character, though, he excels, being unknowledgeable about the setting and therefore able to bring up the ridiculous qualities of Novaria and the fantasy genre as a whole while also being involved in a fantasy story that revels in being that same genre. It smacks a bit of other fantasy humorists, probably more like Pratchett than Anthony, because the humor here is very much in the way the characters go against fantasy clichés instead of playing it more seriously as Xanth does (and I know that sounds odd, but if you’ve read all of them, it should make sense).

The humor, then, largely lands, though there is the slight sense that some of the story is dated in an older sort of fantasy, one that hasn’t necessarily survived to the current times. Still, as someone who has read and taken in a lot of fantasy from that time, I can see the allure, and I can get the humor. The characters alone are worth the read, because the book is filled with colorful people, all of them being kind of nasty in their own particular way. It plays on the idea that people are really only out for themselves, for their own interests, that humans in general seem too complicated, too full of plots and intrigue, a point that couldn’t be as well made with a human main character.

Other than that, my only real complaint is that the book doesn’t really do women any favors, largely leaving them out and only briefly making fun of the tropes in fantasy to have the women be virginal and pure. I would have liked a bit more, and I understand that this was written a long time ago, but some of the jokes are obviously playing towards a male audience and it made me a bit sad to see. Still and overall, though, the book hits the right notes. Though some the jokes miss, enough hit that I can put this up there with works by Pratchett and Anthony. And while it might not be groundbreaking, it was at least a fun book to read.

So in the end, this was a book that made me smile often enough, though it didn’t actually make me laugh. It takes a bit to make me laugh, though, and part of the problem was the somber tone of the narrator, which I understand completely. It is a well crafted book, and a short book, and really I don’t have all that much more to say for or against it. I enjoyed it, and for that at least it earns a 7.5/10.

A fun read, filled with gleefully obscure terminology and a skewering of fantasy tropes and human foibles. It's become increasingly clear to me that the greatness of The Compleat Enchanter series was due to De Camp, not Fletcher Pratt.

Edited to add: Re-reading it four years later, the book is marred by the glaringly racist threat of the cannibal black army. My fun definitely took a nose-dive at that. Even by the 70s, that should've been readily apparent as problematic.

This book is a lot of fun, the tale of a demon named Zdim who is from what mortals call the 12th plane who allows himself to be summoned to the prime plane. There, he is contractually obligated to follow the orders of those who summoned him (or to whom his contract is sold), and so he does follow them . . . to the letter, even if this causes more problems! Fun stuff, and I can see clearly why it was on Gary Gygax's "Appendix N" list . . .

It's a book about a demon that enters a medieval fantasy version of our world through the typical summoning contract. It starts off with a fun premise, then slows down for the demon's first few contracts--for he bungles through them one by one with well-meaning ignorance--before really picking up at the final arc. I enjoyed it, mostly. Reframing real life issues and cultural values through an outsider's very literal perspective was fun. Some bits--particularly the ones involving the avaricious Syndics and the entitled Prince Hvaednir--left me with the vague sense that I should be offended for humans, but all I could do was shake my head and snort. I'd recommend this book to a philosopher.

An older, classic fantasy humor book, sort of pre-Pratchett. Zdim the demon is conjured to the swords & sorcery world as an indentured servant to a mage, and promptly begins a long series of goofing up while legitimately trying to follow the strict interpretations of fallible human commands. There's a large-scale city siege and a lot of hacking and slashing (and biting, on the part of Zdim), but the pointy thrust of the book is what nutjobs humans be. Zdim's bewilderment and confusion about human customs and habits and profit-mindedness gives the book its humor and the lead character his personality. Imagine Spock in the body of a lizardman, plopped down into Conan's world, and you have The Fallible Fiend.

This is a fun, and short, book, that takes the demon’s point of view. Wizards oft complain about the literalness of demons and come up with all sorts of outlandish theories ascribing maliciousness to the demons who so literally take their commands that the commands become worthless. Here we see that from the demon’s side.

There is also a definite D&D-ish vibe in the writing, which is not surprising: this doughty author is on the infamous Appendix N. From the kind of humor to the language to the spells, readers of first edition AD&D or early Dragon articles will find this a familiar, even nostalgic, territory.

L. Sprague de Camp writes in an engagingly humorous style that rarely disappoints. This title is my favorite of his. The 'fiend' is one of funniest characters I've ever come across in the field of fantasy. I reread this from time to time, as a pick-me-up.

So this is what passed for humorous fantasy before Terry Pratchett. If it was just not funny, I might have given it two stars, but what with the unabashed racism and "humorous" rape scene, I'd give it 0.5 stars if I could.

Decent quality classic fantasy with some interesting additions to the field (and some that were borrowed and extended by D&D), especially when you put them in temporal context. However, it shows its age with respect to the use of offensive cultural tropes.

Pretty enjoyable, although the demon taking everything seriously with humorous consequences got a little tired by the end.

"The Fallible Fiend" is a spin-off of L. Sprague de Camp's "The Reluctant King" trilogy; while the story takes place in the fantasy setting of "The Goblin Tower" and "The Clocks of Iraz," it deviates from the story of King Jorian and the wizard Karadur and instead focuses on a new protagonist, Zdim, a demon from the Twelfth Plane.

This entry in de Camp's Novarian series retains the humor and light-heartedness of its predecessors, and also includes some excellent and compelling worldbuilding. Moreover, the characters are as silly and eccentric as ever, furthering the comparisons of this series to that of Pratchett's "Discworld" novels. Even further, de Camp continues the theme of diverging from established fantasy tropes through the behavior of his protagonist, as well as through the behavior of the denizens of Novaria (I will not include specifics in this instance, as they could tread through spoiler territory).

While these positive qualities persist in this novel, "The Fallible Fiend" doesn't seem to hold up to its two predecessors for a number of reasons. One glaring reason is simply that Zdim, the demon protagonist of this novel, isn't as compelling a character as King Jorian in the previous two books. Another flaw for "The Fallible Fiend" would be that the plot doesn't find itself until nearly halfway through the novel; indeed, the ride through the story can be great fun (although it does meander at some points), but it isn't very significant, especially compared to the story of King Jorian.

For this novel, I would specifically recommend it to fans of Sword & Sorcery and fans of L. Sprague de Camp in general; I would say for fans of fantasy in general to start at the beginning of the series or to just mainly focus on "The Reluctant King" trilogy before bothering with this novel. However, it should be stated that this novel can be read separately from the rest of the series as it is a spin-off, and the protagonist was very purposefully written in a way that he is an outsider to the world of Novaria, so new readers can use this novel as an introduction to the series.

This is why I never make all the much progress on my 'to read' pile. I got this (along with a few others) when I was hunting for Pokemon cards for my nephew. I just couldn't pass up that awesome cover, and I've been meaning to read more de Camp (Mostly I've just read his Conan stuff).

This book was a super fun story of the demon Zdim, who is forced to come to our plane for a year to earn some Iron for his community. So he leaves his wife and her eggs to do be the servant of a wizard.

Demons, being logical and practical being, aren't really used to human not really saying what they mean, so Zdim's taking orders literally causes a bunch of trouble and he runs through a few masters (turns out his contract is transferrable) until he ends up in a besieged city and being sent to negotiate for help to break the siege.

Zdim's adventures are quite fun... he's a big scary demon, but also a very polite guy and a philopospher and argues his way out of most trouble.. he only had to eat people a couple times.

The different governments and people of Novaria are quite fun... the city Zdim finds himself in is run by merchants... then there's one where the ruler is chosen at random every year (the year of the story the person was less than ideal) then there's some nomadic tribes.

The bad guys are cannibals from across the sea on a 'foraging expedition'.. they thing war is awful and since the Novarians always attack each other, their best use is food, so they have arrived to eat them all. I have to say this is the first time I read a book that tried to make cannibalism seem ok.

All and all a fun book that I'm glad I picked up.

Der Dämon Zdim wird auf der 12. Ebene dazu zwangsverpflichtet, wie alle erwachsenen Dämonen zum Beschworen werden bereitzustehen, um im Gegenzug notwendige Rohstoffe in Form von Eisen für seine Heimat zu erwirtschaften.
Da seine Frau gerade Nachwuchs erwartet, passt ihm das zwar nicht, aber was will man machen...
Nachdem er von einem Zauberer auf die Erste Ebene - die der Menschen - beschworen wird, versucht er, seinen Vertrag so gut und genau wie möglich zu erfüllen. Aufgrund wörtlicher Befolgung eher undurchdachter Anweisungen führt das bald dazu, dass sein Meister seinen Vertrag weiterverkauft. Damit beginnt für Zdim eine Abenteuerreise, die ihn über den Zirkus in eine Position bringt, wo er als Unterhändler für eine von Kannibalen belagerte Stadt Verbündete werben soll. Dabei gerät der Dämon von einer misslichen Lage in die nächste.
Zdim, der als Student der Philosophie die irrationalen Erstebener studiert hat, hat dabei ausreichend Gelegenheit, über die Absonderlichkeiten der verschiedenen menschlichen Völker und ihrer Vertreter zu sinnieren.
Kurzweilig und relativ schnell zu lesen.

I got this one from a lot purchase on eBay. de Camp has a long history of non-stereotypical Fantasy, which is refreshing in a genre with so many hackneyed elements. Set in a fairly standard world before Tolkien re-defined the center of gravity in fantasy (think Fafhrd and the Grey Mouser), Zdim is a demon. He was summoned for a period of servitude, but has a series of adventures that quickly depart from any standard story. Zdim was a philosopher on his plane of origin, and he travels through a human world with wry observations about humanity. The yarn evoked some chuckles from me, and appreciation of its unconventional nature. On the other hand, it wasn't particularly great writing or personally insightful, and I won't be exploring further in the series.

A demon is contracted for a year of service on the human plane of existence. The lot falls to our main character and Zdim must leave his wife and egg to serve a magician.

He strives to follow directions, but humans are lousy at giving directions. Although Zdim tries to follow them to the letter, disasters often follow.

The tale takes him from one "owner" to another and one adventure to another. Each adventure more involved than the last.

Fun reading. The book went by too fast and I was left wanting more.

If you're reading through the mass of Appendix N literature, you're going to hit more than your share of dodgy wizards summoning all forms of foul demons from beyond. This novel is novel in that it takes the viewpoint of the foul demon being summoned. It crafts a beautiful backstory for a perfectly reasonable and amiable guy who gets summoned for the good of his community and has to deal with stupid, imperfect and imprecise humans who are continually unhappy with getting what they asked for.

A humorous satire of the games we play, deCamp expresses his themes very well. Ever present is is love of using two-dimensional, Aristotalian logic to every situation. Very adult and very funny. The only flaw was that I felt it bogged down somewhat about three fourths of the way through with situations that were almost repetitive. Nevertheless, I enjoyed the work overall. A good rread.

The Fallible Fiend by L. Sprague de Camp.
A humorous fantasy novel. Zdim the demon is conjured by a mage to be his indentured servant (in exchange for iron which is rare on the demon home plane). He makes many mistakes while legitimately trying to follow the strict interpretations of fallible human commands.
