Reviews

The Washington Post Kahn has produced a tour de force...The volume is an anthology of a hundred detective stories, one more ingenious than the last, and all real, central to the fate of armies and kingdoms....Magnificent.

The Christian Science Monitor A literary blockbuster...for many evening of gripping reading, no better choice can be made than this book.

Time Perhaps the best and most complete account of cryptography yet published.

The New York Times Book Review A notable achievement...Mr. Kahn has presented the specialist and the general public with a lavishly comprehensive introduction to a subject of basic significance for both.

Prepublication National Security Agency Evaluation, now declassified The book in its entirelty constitutes the most publicly revealing picture that has ever been presented of U.S. Sigint activities and the agencies engaged in this field.
