Betrayal 

In book seven of the Warren Steelgrave series, Warren has settled into a comfortable life in a small village in Northern Italy. Suddenly all that changed. Carlo Mattia, the son of Brigadier Mattia, has gone missing. Carlo and his partner Enzo were part of the international task force investigating worldwide sex trafficking. When Enzo turns up dead, and Carlo goes missing, Brigadier Mattia needs a favor from Warren Steelgrave, who owes him a few.

Warren is soon in over his head, having been given a hard drive containing evidence that implicates the corruption of many important people. The hard drive exposes corruption in the FBI, the international task force, and many in government. There is no one Warren can trust as he tries to get to court and testify.
