Spies and assassins. Both live in the shadows, travel under assumed names, adopt multiple identities, and do the bidding of others. They can be one and the same, two sides of the same foreign coin. Patriot and killer; ready and able to dispatch their targets unemotionally.
Our challenge as thriller writers? To create believable plots and imbue both characters with equal dimension and appeal.
