James Leasor was educated at The City of London School and Oriel College, Oxford. In World War II he was commissioned into the Royal Berkshire Regiment and posted to the 1st Lincolns in Burma and India, where he served for three and a half years. His experiences there inspired him to write such books as Boarding Party (filmed as The Sea Wolves) and The One that Got Away, the story of the sole German POW to escape from Allied hands. Passport to Oblivion, part of the Dr. Jason Love book series, was published in nineteen countries and was filmed as Where the Spies Are with David Niven.
