Acknowledgements
I wish to thank particularly my wife, Jill, for her strict and expert editing of the book, and for her initial suggestion that I attempt this story.
My thanks, also, to GH who acted as captain of the submarine HMS Proteus, and to the Royal Navy, without whose assistance, given so freely and willingly, I could not have completed the book. Gratitude, too, to TRJ for coming to my assistance in developing the "Leopard" anti-sonar equipment on which the story hinges.
As usual, I am indebted to various publications, particularly to Breyer & Polmar't Guide to the Soviet Navy, Labayle & Couhat't Combat Fleets of the World, and The Soviet War Machine, edited by Ray Bonds.
Any errors, distortion or licence for dramatic purposes is my responsibility, not that of any of the above.
About the Author
Craig Thomas has been described as "a master storyteller" and "one of the finest action writers working today". His fourteen best-selling novels have consistently attracted praise and that sincerest form of flattery, imitation, since he is generally credited with creating the genre of the 'techno-thriller' with his novel FIREFOX (1977).
