Is it possible to write a mystery story without revealing who the culprit is?

There will likely be clues throughout the book pointing to a certain character, but that character is not actually caught or revealed to be the culprit. The point would be for the audience to guess and ultimately decide for themselves which of the characters was the true culprit.

P.S. Feel free to let me know of any known mystery novels that do not reveal explicitly who the culprit is. I would be very interested in reading them.
