No Remorse by Zena Oliver

Playing with fire can get you burned … or killed.

Chase Effridge, the handsome young playboy/college professor, is dead. A devoted and faithful husband he was not. Professor Effridge led a secret life, where mistresses and enemies were no strangers to him. When his secrets began to surface, his seemingly perfect life took a turn for the worse. One mistress with a baby, and another whose boyfriend found out about their affair, were the equivalent of adding fuel to the fire.
Effridge’s estranged wife, Carlotta Dupree, tops the suspect list, but swears she’s innocent. Her cold demeanor and ill-wishes toward her husband do nothing to help her story. She claims to have an alibi, but can it be verified?
The list of suspects keeps growing as the interrogation process proceeds. Each conversation does little to unravel the complexity of Chase’s life, and provides little clarity as to who can be eliminated and who can’t. Instead, the discussions tend to reveal a new person of interest, and shroud those already on the list with more suspicion. Everyone seems to have a motive.

Will this crime ever be solved?
