Answer:
personification
Explanation:
The term 'personification' means to attribute any human characteristics or nature to some non human objects. It represents an abstract quality. It is a metaphor in which an abstraction or a thing is being represented as a human being.
In the context, death is being compared with a person and the narrator says that 'death' had stalked the victim which is a metaphor. As 'death' is not living person so it cannot stalk anybody. Thus this is an example of a personification.
