Walter Marsh with the surreal tale of Colin Wyatt, the ski champion, mountaineer, wartime camouflage expert, artist, and naturalist who committed one of the world's biggest-ever museum heists in the 1940s.

In January 1947, by chance, it was found that over 3,000 rare and precious specimens of butterflies had vanished from museums in Sydney, Melbourne, and Adelaide. 

Alarmingly, the missing insects included many priceless ‘holotypes’ — the first specimen of a given species to be identified, against which all others are compared.

On the other side of the world, New Scotland Yard descended on a nondescript country house in Surrey, where they found a trove of over 40,000 butterfly specimens. 

The culprit was Colin Wyatt, a Cambridge-educated ski champion, mountaineer, wartime camouflage expert, artist, and amateur naturalist whose high-flying exploits cut a path from the Alps of Europe to a London court room to a final expedition to the jungles of Guatemala.

Walter Marsh has written down the strange and confounding tale of the gentleman butterfly thief in his new book.
