Start with The Maltese Falcon. It is the book every private-eye novel written since has been answering, it runs about two hundred pages, and it is the purest demonstration of the technique that made Hammett matter: the camera never goes inside anyone's head. You watch Sam Spade the way the other characters watch him, and you work out what he is doing at the same speed they do.
The competing recommendation is Red Harvest, his first novel, and it is a defensible choice — faster, nastier, and closer to the pulp magazines he came out of. Read it second. Starting with The Maltese Falcon is better because the objective style is a genuine adjustment, and Falcon executes it with the fewest moving parts. Once you have adapted, Red Harvest hits much harder.
The five novels, in order
Hammett published all five between 1929 and 1934, so publication order and chronological order are the same question, and there is no series continuity forcing your hand. The sequence worth following is:
Red Harvest — the nameless Continental Op arrives in a corrupt mining town and sets its factions to killing each other. It is the most violent and the most political of the five, and it moves like something falling downstairs.
The Dain curse — the weak one, and it is worth saying so plainly. It was stitched together from four separate pulp serials, and it reads that way: three near-complete plots bolted end to end, with a supernatural middle section that resolves into anticlimax. Skip it without guilt if you are reading for pleasure rather than completeness.
The Maltese Falcon — the one you started with.
The Glass Key — Hammett's own favourite, and increasingly the critics' too. A political fixer investigates a murder that implicates his patron. It is the coldest of the novels, the least generic, and the one that most rewards a second read. If The Maltese Falcon worked for you, this is the next essential.
The Thin Man — the last, the lightest, and the outlier. Nick and Nora Charles drink their way through a New York Christmas, and the detection is almost incidental to the banter. It spawned a film franchise and a whole tone. Some readers find it a charming farewell; others find it a slackening. Both readings are fair.
The short stories
The big knockover collects Continental Op stories, and it is where the method was invented. The Op is fat, middle-aged, unnamed and entirely without romance, which is exactly what makes him the antidote to the detective heroes that came before. Read the collection after the novels rather than before — the stories are compressed and repetitive in bulk, but individually they are as good as anything in the genre.
Two books for context
The simple art of murder is Raymond Chandler's essay collection, and its title piece is the most famous argument ever made for the American crime novel over the English country-house puzzle. Chandler is describing Hammett more than himself, and it is short. Hardboiled America by Geoffrey O'Brien places the whole thing in its paperback-and-newsstand context, which is genuinely useful — this fiction was a mass-market commercial product before it was literature.
Where to stop
After The Thin Man, because that is where Hammett stopped. He published no further novels in the remaining twenty-seven years of his life, spending them on screenwriting, political activity, and a jail sentence for refusing to name contributors to a bail fund during the McCarthy period. There is no late phase to catch up on. Anything else you find under his name is uncollected pulp work or posthumous fragments, and none of it changes the picture.
Five novels in five years, and then nothing, is a strange shape for a career. It also means the whole essential body of work is about a thousand pages — a fortnight of reading for the foundation of an entire genre. Browse more reading paths if you want to follow the tradition forward.
