To Prove a Villian - The Shakespeare Murders, #3

When Mark Louis investigates the hit-and-run death of the brother of Kristy King, his live-in lover and colleague in their downtown NYC acting troupe, it unexpectedly puts a fatal strain on their relationship. Kristy insists the death was an accident; Mark isn't certain that's true. The deeper he digs into the incident, the more he learns of Kristy's background and the wider the gulf between them grows.
Kristy's mom gets involved and the problem only deepens. Mark's suspicions prove to be accurate, and the price for finding the murderer is a secret he must keep locked in his soul and take to his grave.
