In the spring of 2005, Guy Enright, an accountant at KPMG Financial Advisory Services Ltd. in Bermuda, got a call from a man identifying himself in a crisp British accent as Nick Hamilton. Hamilton said he needed to see Enright about matters of utmost importance.
Over the course of two meetings, Hamilton led Enright to believe he was a British intelligence officer, according to a person familiar with the encounters. He told Enright he wanted information about a KPMG project that Hamilton said had national security implications for Britain. Soon, Enright, who was born in Britain, was depositing confidential audit documents in plastic containers at drop-off points designated by Hamilton.
