Read Again? Maybe
The third short story in the "Trouble Is My Business" collection.
Carmady wakes up to find a man with a gun in his bedroom; it's an acquaintance on the run from some bad guys.
The man gets aced by some thugs with a chopper, so now Carmady's looking for the killers and their bosses...
...and this brings us to a matching scene from "The Big Sleep," where Marlowe went to visit a sick old man who wanted his son-in-law found, had a followup discussion with the old man's daughter, and then a run-in with the house sociopath (Carmen in "Big Sleep," a little boy in this one).
Both "Curtain" and "Killer in the Rain" (1935) were the basis for 1939's "The Big Sleep;" two of his other novels--"Farewell, My Lovely" and "The Lady in the Lake" are also built from earlier short stories. While it was confusing at first (while reading "Killer in the Rain"), and disappointing because now I knew what was about to happen, it's still fascinating to see how Chandler plugged slightly different characters and situations into these pieces.
