Query: A superb novel of intrigue that should be made available!

This book was reviewed on the front page of the New York Times Book Review section when first published, and Tyler was hailed as a writer comparable to Graham Greene or John Le Carre. It is a classic novel of espionage set in the newly emerging nations of Africa in the 1960's. Tyler writes elegant, compact prose with fine plotting and character development. He also writes with the authenticity that comes from a career working for the State Department in Africa. It is a pity that this book and his book Ants of God are both unavailable
