The Last Shot Is for Revenge: A Dan Ryan Mystery

Private Investigator Sally Reed is accused of murdering her husband. No one believes she pulled the trigger, but to advance his political ambitions, the District Attorney is coming down hard for a short investigation and a quick trial with a conviction.
PI Dan Ryan won't let that happen. Sally Reed was Ryan's partner and lover before she married a man she had once been engaged to. Pulling strings with a powerful drug boss, a prostitute ring, and a private gay men's night club along with a bookie with secrets and the police investigating detective, he plows into the case.
Dan Ryan is like a Pit Bull gripping the DA's leg to help a famous defense lawyer discredit the evidence against Sally Reed, but long-standing revenge and justice face off for the last bullet.
