Chicago private eye Cat DeLuca, founder of the Pants on Fire Detective Agency, was briefly married to runaround Johnnie Rizzo. Her experiences gave her the mad skills she needed for her agency: she only investigates cheating husbands. So why, when someone kidnaps Captain Bob's dog and claims to have evidence of cop corruption, does Cat's Poppa not only deny the accusation, but order Cat to leave it alone? The answer may lie in an unsolved hit-and-run death that was relegated to a dusty cold case file.
