Double Crossed

Ronan McCullough is still recovering, physically and emotionally, from his last case and trying to rebuild his life. Then a federal agent's charred remains turn up, tied to a professor's encrypted money laundering scheme. Ronan is pulled into a deadly contest with someone prepared to kill anyone who knows anything about the encryption codes.

As he digs, Ronan finds dark secrets and realizes that no one is being straight with him, including the people he trusts most. When the codes are stolen, he learns what they are really for. He now has to stop a plan that would make it close to impossible to cut off the funding of dangerous crimes.

The body count climbs and more secrets come to light as Ronan works his way through a web of deception toward the truth. His problem is that the main suspect is a set of numbers.
