The Green-Eyed Monster

Set in middle/upper class Manhattan. When the main character's wife is murdered, suspicion goes from person to person in their families until the last chapter (<a href=http://goodreads.com/book/show/993287>Good Reads</a>).

Andrew Jordan might be called an everyman—if it meant that every man drifts through life in a perpetual haze of boredom, a completely bland creature married to a woman who neither appreciates nor loves him. Even the series of anonymous messages warning him of his wife’s infidelity spark nothing in him except a belief that whatever is wrong must be his fault.
Then his wife is murdered, and the meek Andrew is a prime suspect.
With no one to turn to, Andrew begins his own investigation, discovering there were more than a few people who had it in for his wife. The more he learns, the more he realizes someone is setting him up for a big fall.
And if he doesn’t stand up and prove his innocence, they are going to succeed. (<a href=http://mysteriouspress.com/products/edgar-award-authors-winners-and-nominees/the-green-eyed-monster-by-patrick-quention.asp>Mysterious Press</a>)
