Death in Divorce, a Jake Curtis / Vanessa Malone Mystery

Sixteen hours after winning her divorce from her cheating husband, Blanche Bickers was found, by her maid, naked in her bed and dead, with a raw bullet hole in the center of her forehead. With no eyewitnesses to the murder and only forensics evidence to go on, the police were baffled. No one saw anything.
Jake Curtis, Private Investigator, and his partner and wife, attorney Vanessa Malone, are hired to defend the victim’s ex-husband, John Bickers for her murder. It was a simple job. All it took was good old fashioned legwork. A tour thorough the victim's BFF's, the BFF's husbands, assorted family members and other miscellaneous interlopers led down trails from dead end o more dead ends. No one knew anything. Jake Curtis and Vanessa Malone verified their client's alibi and forced the police to release him and look elsewhere for the murderer. Jake and Vanessa worked on the premise there were only two people in Blanche's bedroom when she died; Blanche and her murderer.
Based on the the victim's first ex-husband, Marshall Evans', admission that he'd been with the victim only hours before the murder, the police arrested him. Barbara Evans, Marshall’s current wife hired Vanessa to defend her husband against the murder charge. Jake and Vanessa believed him to be innocent.
Was it because of Blanche's string of lovers that got her murdered or was it only one of her many lovers? Questions pile up but answers still remain allusive. Our diligent private investigating team persevere deeper and deeper into the labyrinth of this case in search of the murderer.
Repeated interviews with family members and BFF's revealed a Southern Belle who said something about the murder to Jake and Vanessa that no one outside of law enforcement knew. The BFF steadfastly refused to divulge who told her the one thing she shouldn't of known caused Jake and Vanessa to reinterview the BFF time after time, each time more forceful and the last. The threat of turning the BFF over to the police as the actual killer convinced her it was in her beat interests to reveal who told her the unreleased fact. What she told Jake and Vanessa led to the killer and to the surprising reason why the murderer killed Blanche Bickers.
