What Happens, Part by Part (Contains Spoilers)
An unwanted case
Nick and Nora are in New York for the holidays, enjoying parties and cocktails. Dorothy Wynant, the grown daughter of Nick's old client Clyde Wynant, asks Nick to help find her father. Nick has given up detective work and refuses. Then news arrives that Julia Wolf, Wynant's secretary and former lover, has been found shot in her apartment, and everyone assumes Wynant did it.
A strange family
Wynant's ex-wife Mimi, who found Julia's body, and her new husband Chris Jorgensen push Nick to get involved. Their children, Dorothy and the odd, questioning Gilbert, keep turning up at Nick's hotel. The police, led by Lieutenant Guild, suspect Nick knows more than he says. A small-time crook, Arthur Nunheim, claims to have information and is shot dead soon afterwards.
Letters and lies
Macaulay, Wynant's lawyer, keeps receiving letters and telegrams that seem to come from Wynant, accusing others and promising to appear. Nick learns that Jorgensen is really a former employee of Wynant living under a false name. Mimi lies about evidence she took from the murder scene. Every lead seems to point back to the missing inventor.
The body in the shop
The police search Wynant's old workshop and find a buried body, dressed in the clothes of a much heavier man. Nick realizes the clothes were planted to hide the truth: the body is Wynant, the “thin man” of the title, who has been dead for months. Whoever is writing the letters in his name is the killer.
The solution
Nick explains that Macaulay had been stealing Wynant's money with Julia's help. When Wynant found out, Macaulay murdered him and then forged letters to keep him “alive” as a suspect. He killed Julia and Nunheim to protect himself. Macaulay is arrested, and Nora complains that the solution is not nearly as satisfying as she had hoped.
5 Key Takeaways
- The most obvious suspect may be the first victim.
- Charm and wit can hide a sharp mind at work.
- Greed drives almost every character in the story.
- Marriage can be a true partnership of equals.

Ideas Worth Remembering
