In the novel, not all the crimes committed by Mr. Hyde are told. However, Dr. Jekyll, at the end of the book, hints that he committed several to quench his thirst for evil.
Only one of them is described in the novel. It happens when Mr. Hyde is in the street with Mr. Carew, and the latter asks him for directions to get to a place, but Hyde quickly loses his temper and beats him to death with a cane.
