Alliteration

Explanation:

Alliteration refers to a literary device in which an author employs a number of words with the same initial consonant sound closely together in a sentence. Alliteration provides a sense or rhythm and musicality to a sentence. In this example, the author employs alliteration in cases such as "murdered ... moved," "watcher ... waiting" and "wrenched ... wrestled."
