Final volume from Patrick Leigh Fermor

John Murray is to publish a posthumous book by travel writer Patrick Leigh Fermor, who died in July.

The book will complete the story of the journey Leigh Fermor made on foot from the Hook of Holland to Constantinople at the age of 18, as told in his previous works A Time of Gifts and Between the Woods and the Water. The currently untitled volume will be published in September 2013.

Artemis Cooper, whose biography of Leigh Fermor will be published in September 2012, said: "By the end of the second volume, he was about to cross the Danube from Romania and plunge into Bulgaria; and his devoted readership have been stuck midstream, as it were, for over 20 years. A painstaking perfectionist, Leigh Fermor never did finish the final volume though he was working on it up to his death in June 2011."

Based on the original diary he kept at the time and an early draft of the book written in the 1960s, this book takes up the story, and carries the reader to Constantinople and beyond.

John Murray m.d. Roland Philipps said: "I was told of the existence of a manuscript on the day that Sir Patrick died in June of this year, and read it shortly afterwards. It is a  treat to be back, immersed once again in this great pre-War walk across Europe and wonderful for his many admirers that this book will be published."

The publisher describes Leigh Fermor as "one of the outstanding prose stylists of modern time".
