Tad Anders is an assassin for MI-6.
Tadeusz Anders, who goes by Tad, was the son of a Polish soldier, a member of the Free Poland underground, who was had fled a German concentration camp and was in England preparing to return to the Continent. The soldier met and fell in love with an English woman, they were married almost immediately, and in 1940 Tad was born. Three years later, his father was killed at Monte Cassino and Tad became the only man in the family. Though he was raised by his mother in the small English village, that town also housed a Polish community where he learned to speak Polish and Russian as a native.
At 18, he was accepted into University but chose a different path. It was the announcement by his mother that she was marrying a farmer who lived near them that changed his mind. Unhappy that his mother was abandoning the memory of his father, the day after the wedding he packed up his belongings and his father's medals and left home. He joined the military to be like his father.
In the army, the knowledge of Russian and Polish he had learned as a child got him admitted into the Intelligence community and it was not long before the SIS approached him. Though he had risen in rank in the army, having become commissioned and getting to the rank of Major, the appeal of the clandestine services was enough to get him to join their forces. They were very pleased to snatch him up and found in Tad Anders a man of 'singleness of purpose' who would let nothing or no one stand in the way of success of the mission.
Most telling about the character is an odd statement in that, despite his good looks and charm, few men saw in him a rival. Furthermore, while many women saw in him a good husband, none saw a lover. He refused to get close to another woman for fear of being betrayed as he felt he had been by his mother. And he never saw his mother again.
