George Thomas was a banker, and a friend of Duncan MacLeod's. He had retired and passed his days playing bocce and didn't like it, "One day you're changing your grandson's diapers, and the next thing you know he's managing your bank." He had a lot of time on his hands and he began thinking and reading, wondering if it were only good deeds that define a man's soul.
After a game of bocce with MacLeod one morning, he was killed by a car bomb, and MacLeod discovered that he'd been being watched by Alex Raven.
She was in search of money deposited at the time of the Second World War by victims of the Holocaust. George's grandson, Grant Thomas, eventually revealed that he had his grandfather killed because the old man wanted to give back the money deposited by Jews during the war, the money Alex had been searching for.
