Robert B. Parker's Grudge match - Mike Lupica

When Sunny Randall's long-time gangster associate Tony Marcus comes to her for help, Sunny is surprised - after all, she double-crossed him on a recent deal, and their relationship is on shakier ground than ever. But the way Tony figures it, Sunny owes him, and she is willing to consider his case if it will clear the slate. Tony's trusted girlfriend and business partner has vanished, appearing to have left in a hurry, and he has no idea why. While Sunny isn't willing to trust his good intentions, the missing woman intrigues her - against all odds, she's risen to a position of power in Tony's criminal enterprise. But when a witness is murdered hours after speaking to Sunny, it's clear there's more at stake than just Tony's love life.
