Thick as Thieves by Sandra Brown

Twenty years ago in the dead of night, four seemingly random individuals pulled the ultimate heist and almost walked away with half a million dollars. But by daybreak, their plan had been shot to hell. One of them was in the hospital. One was in jail. One was dead. And one got away with it.

Arden Maxwell, the daughter of the man who disappeared all those years ago — presumably with the money, after murdering his accomplice — has never reconciled with her father’s abandonment of her and her sister. After countless personal setbacks she decides to return to her family home near mysterious Caddo Lake, and finally get answers to the many questions that torment her. Little does she know, two of her father’s co-conspirators — a war hero and a corrupt district attorney — are watching her every move.

Ledge Burnet, a rebellious teen at the time of the heist, evaded his jail sentence by enlisting in the army. Now he’s back in town to care for his ailing father — and to keep his eye on the county’s corrupt district attorney, whom he suspects was the real murderer. Although the two are bound to silence because of the crime they committed together, each has spent years waiting and hoping that the other will make a fatal misstep. But the arrival of their elusive accomplice’s daughter, Arden, who may know more about the missing money than she’s telling, sets them both on red alert. She ignites Ledge’s determination to expose the D.A.’s treachery . . . and sparks a desire he wishes to deny.
