The guise of another

the long version

Alexander Rupert, a Minnesota detective and Medal of Valor winner, is under subpoena by a grand jury on suspicion of corruption. Reassigned to the Frauds Unit, he is shunned by his fellow detectives, and he fears his wife may be having an affair. When he happens across a complex case of identity theft, Rupert sees an opportunity to rehabilitate his tattered reputation. But the case puts him in the path of trained assassin Drago Basta, who has been searching for "James Putnam" for years.
