Mark One

Ed Nesbitt has a problem.
Nesbitt is the author of dozens of phenomenally successful suspense novels starring that lethal super-agent of the West, Mark Day, master of karate and aikido, and irresistible womanizer. Everyone loves his books-"So realistic," they say; "Day is so true-to-life." The problem is: he's too realistic. Everyone thinks Nesbitt is Mark Day. Even the enemy. And the enemy means to do something about it.
Which explains what the large man with the very sharp knife is doing in Nesbitt's hotel room in Berlin. Which explains why Nesbitt's luggage and possessions are being ransacked.
Which does not explain what happens the next moment, when Ed Nesbitt quite suddenly finds himself transformed into a man three inches taller, several years younger-and possessed of some of the most awesome fighting capabilities the West has ever known.
Ed Nesbitt, meet Mark Day. You're about to save your own life-in a most remarkable fashion.
