who was murdered, and why is victor accused of the murder?

The creature has murdered Henry Clerval. A crowd of people observes Victor's approach with suspicion as Victor shows up just after Henry's body was discovered in the water; they rain verbal abuse upon him and cry that he is a villain. A bewildered Frankenstein is told that he must go see the magistrate, as he is suspected of being responsible for the death of a man who was found murdered the previous night.
