Dead Detective by Robert Wise

Sam Sloan is dead. But when his wife, Vera, receives the report of his plane going down, she flies to the site and finds no evidence of a crash. Unable to put the puzzle together, Vera and her daughter, Cara, struggle to accept the reality of Sam's death. But when mother and daughter find a computer disk in a hidden "stash" in Sam's office, they stumble onto the man responsible for his death-Ivan Trudoff, a money-laundering member of the Russian mafia. Armed with the promise that God's help comes in the midst of confusion, Vera is determined to go after the criminal herself.

But will Vera find the justice she seeks-or will she unknowingly move toward a dangerous confrontation?
