The Blackbird (1969) – Macmillan

A Grofield Novel

There was no way out of it. Grofield spent the long half hour of the ride back to Quebec thinking about that, learning reluctantly to accept it. There was no way out, he was going to have to try to get the information Ken and his buddies wanted, and at the same time keep that other bunch from kidnapping him again, and at the same time keep Marba and General Pozos from finding out he was actually working for the American government. A juggling act, that’s what he was going to have to perform, simply because there was just no way out of it. They had him in a cage.
