This new edition contains a new Afterword by the author, an Introduction by Loren Coleman, and a Preface by Bernard Heuvelmans, the "father of cryptozoology," who wrote: "Peter Costello authoritatively surveys the whole subject, supporting his arguments with a substantial bibliography, and displaying both the elegance of the born writer and the sense of humor essential to every occasion."
"Peter Costello makes a fascinating, sometimes frightening case for the existence of Loch Ness-style 'monsters' in a number of freshwater lakes around the world... There's enough here to unnerve the most hardened skeptic..." - Jerome Clark, Minneapolis Tribune
"An infectiously enthusiastic reappraisal." - Sunday Telegraph
"Certainly... the whole work is impressive, and it would seem to be a safe bet that Mr. Costello's book will become a standard reference for anyone interested in its perennially fascinating subject." - The Canberra Times
"It is the world-wide perspective that makes this book worth reading." - New Scientist
