'If you are watching this videotape then I am dead ...' Yesterday, David Tennant was a highly respected Ethicist with the ear of the President, working on a top secret Government project. Yesterday, he was a man recovering from personal tragedy, just learning to live again. Yesterday, he was falling in love. Today, he is running for his life. Project Trinity has the power to change life forever. Only a few, handpicked men and women know the potential of the biggest artificial intelligence study the world has ever seen. Now, one of those men is dead - and Tennant knows Dr Fielding's death wasn't all it seemed. Suddenly his friend's warnings cannot be dismissed as paranoia. They are the only reason that Tennant is still alive. Today, David Tennant is one man against the state, and he's fast learning the only rule of survival: Trust no-one. Not even yourself.
