Payback [#3] : Ravens trilogy
(Book)

The police have long assumed bigamist and wealthy businessman Ron Raven paid the price of his crimes with his life. But the restaurateur Luke Savarini is convinced otherwise when he sees his former investigator leaving a chic restaurant near Washington, D.C. The case may be closed, but Luke still feels obligated to tell Ron's second wife, Avery. Kate Fairfax is furious that Luke would raise such an absurd possibility to her mother, who's already suffered so much. But once her anger cools, evidence leaves her facing the possibility that Ron is still alive. With Luke's help, Kate is willing to risk everything to find her father, if it means bringing him to justice, once and for all.
