Any Mysteries/Thrillers without any Murder?

I'm debating between a crime novel centered around murder or a different crime, and I was wondering if anyone else had any crime novels without any murder. :)

"The World's End" is one, by Agatha Christie, and I think "The Problem At Polensa Bay" is without murder as well.
Also quite a few of Holmes' cases were problem solving - with no murder.
And there are any number of Thrillers without murder as the central crime.

I am currently writing a mystery with 2 murders, but the idea of a pure puzzle is certainly intriguing.

D.L. Sayers did this too, in "The Entertaining Episode of the Article in Question" and in:
"The Fascinating Problem of Uncle Meleager's Will" and
"The Learned Adventure of the Dragon's Head" and
"The Piscatorial Farce of the Stolen Stomach"

And my most favourite story of all is without a murder:
"The Insoluble Problem" by G. K. Chesterton.

I'd say if you have a good story, murder or not, then go for it.

My story is the reverse. It's not about who murdered the victim. It's who made the victim suddenly get up and start walking after they were clearly dead.

But it also doubles as a missing persons case since there's no proof that the person being sought has died.
