The Secret Number

In 2000, there was a story called The Secret Number. A mathematician that's been killed at the beginning and his assistant keeps claiming that it was the secret number that killed him because it doesn't want to be found out. It turns out there's a secret number between three and four called bleem. At the very end, there's three jelly beans left on the murder room nightstand. And one of the detective assistant picks it up and is like, hey, look, free jelly beans.
