He was a gentle, polite, elderly person with no more warmth in him than a hangman’s rope. The Agency wits said he could spit icicles in July.

Dashiell Hammet wrote a number of stories about “the Continental Op,” a fat, nameless private detective working for a company based on the Pinkertons, as well as two Op novels. I reviewed the second Op book, The Dain Curse, not long ago, so I thought I might as well do Red Harvest (1929) too. I’d read it before, but way back in the 1970s.

We find the Continental Op in the western mining town of Personville, which seems to be in Utah. The town bears the nickname of “Poisonville,” and well deserves it. It used to be controlled by old Elihu Wilsson, the mine owner, but he’s allowed it to fall into the hands of various groups of criminals (these are Prohibition days, after all). Elihu’s son, Daniel, who has taken over the local newspaper, has decided to be a reformer. He’s requested a detective to come and help him ferret out corruption.

But Daniel is dead before the Op can even meet with him. The Op manages to get in to see Elihu, the old man, and eventually gets his permission to investigate his son’s murder.

Poisonville is in every way worthy of its name. The police are just as corrupt as the various criminal organizations, and as the Op stirs the waters, he finds that poison entering his own soul: “This d**ned burg’s getting to me,” he says. “If I don’t get away soon I’ll be going blood-simple like the natives.” (This is where the Coen Brothers got the title for their movie, “Blood Simple.”)

There is no subtlety in Red Harvest. This is a story about killing, and lots of it. As in Hamlet, the stage is nearly empty at the end, most of the main characters dead, our very unromantic hero still standing, but shakily.

There is a pervasive rumor (denied by director Akira Kurosawa himself) that his classic samurai movie, “Yojimbo,” was inspired by Red Harvest. If so, it would be the grandfather of “A Fistful of Dollars” and a score of other imitators. However, Red Harvest is more complex than those movies. Instead of a scenario with two warring gangs, this novel features a complex situation. There are multiple factions, and the Op busies himself with inciting each of them against the others in various combinations, just stirring things up to see what reactions he can get, increasingly callous to the sanguine results.

When one has grown accustomed to Raymond Chandler’s prose (I can never resist the comparison), Dashiell Hammett comes off as something of a blunt instrument. But Hammett came first, and was breaking new ground, so to speak. Critics consider Red Harvest a classic and a groundbreaking literary work.

But it’s pretty grim.
