''In A Lonely Place'' is a 1950 film starring Creator/HumphreyBogart and Gloria Grahame, adapted from a 1947 novel by Dorothy B. Hughes, directed by Creator/NicholasRay.

Bogart plays Dixon Steele, a Hollywood screenwriter who is commissioned to adapt a novel into a film. Too lazy to read the book, he invites the coat-check girl at his restaurant to his apartment to summarize the book for him. Hours after Steele sends her home, the girl is found murdered in a nearby ravine, and the police latch onto him as the prime suspect. Steele is given an alibi by his neighbor Laurel Gray (Grahame). After being released by the police, Steele strikes up a relationship with Gray, and they soon fall in love.

The police continue to investigate the murder, which puts a strain on their budding romance as Laurel is questioned again and learns about Dixon's history of violent incidents, making her unsure if he's really innocent. As Laurel grows wary of Dixon and he becomes suspicious of her behavior, the tension in their relationship reaches a breaking point.

A bleak thriller, ''In A Lonely Place'' is considered a classic of FilmNoir.

* AcquittedTooLate: [[spoiler:A variation; no judicial consequences are at stake. The real murderer turns himself in anticlimactically, but Laurel and Dix's relationship has already fallen apart.]]
* CrazyJealousGuy: Dix, as the film goes on.
* DearJohnLetter: Laurel writes one when she plans to leave for New York, but has to hide it.
* {{Deconstruction}} : This film is a reaction against other FilmNoir, deliberately moving away from crude murder plots to focus more on the relationship. Specifically, it subverts Bogart's own screen persona, showing how difficult that kind of person would be around and making it decidedly less glamorous.
* DownerEnding : [[spoiler: The couple who are SoHappyTogether break up despite being very much in love.]]
* DuringTheWar: How Dixon Steele knew the detective Brub.
* HairTriggerTemper: Steele.
* FilmNoir: Dark atmosphere, constant suspicions, murder, HumphreyBogart... check.
* TheFriendNobodyLikes : Dix Steele is a tragic accurate version of this, someone who's too paranoid and embittered to be around for a great deal of time.
* FriendsRentControl: Dix is a screenwriter who hasn't had a hit in years, and Laurel has no known source of money except an alluded-to wealthy previous lover. Both have fairly nice apartments in Beverly Hills.
* IncriminatingIndifference: The police suspect Steele quickly due to the fact that he [[TheStoic barely reacts]] to the fact that a woman was murdered minutes after leaving his house.
* InNameOnly: The film is nothing like the novel, and all that is really carried over is the title, the names of the two main characters and Dix's vague occupation.
** Also happens in-story:
-->'''Dix:''' What's wrong with my script?
-->'''Mel:''' Nothing, but it's not the book. And that's what Brody asked for, a faithful adaptation.
-->'''Dix:''' The book was ''trash''!
* MostWritersAreWriters: The film starts out with Dixon being a down-on-his-luck screenwriter who has not had a hit "since before the war."
* NotHisSled: In the original novel, [[spoiler:Steele is a murderer, in the film he isn't]].
* PrettyInMink: Laurel, several times.
* SociopathicSoldier: It's implied that Steele was like this when he served in World War II.
* StuffedIntoTheFridge: An UnbuiltTrope but the main reason the original ending of the book was changed by the director and writer was to avert this:
--> ''"I just couldn't believe the ending that Bundy (screenwriter Andrew Solt) and I had written... Romances don't have to end that way. Marriages don't have to end that way, they don't have to end in violence."''
* StylisticSuck: The book Steele is supposed to adapt sounds just as melodramatic and boring to the audience as it does to him.
* TheMurderAfter: Though the meeting is entirely platonic, Steele falls under suspicion anyway.
* TitleDrop: When Steele is discussing how the crime could have been committed.
* WackyMarriageProposal: Not so much wacky as out-of-nowhere and ''incredibly'' uncomfortable.
* WrongfullyAccused: Dixon is continually suspected of murder despite being cleared from Laurel's alibi.
