Kessel novel film was based on

I've just finished reading an English translation - "The Army of Shadows". It was translated by Haakon Chevalier and published in London by Cresset Press in 1944. Unfortunately it is a library copy. I've been trying to get a copy for myself but haven't had much luck so far. It doesn't seem to be in print and the cheapest 2nd hand copy I've found so far is £25.

The book is a much looser collection of anecdotes - the film pulls some of these together and adds other elements of its own. But they compliment each other. The book is worth tracking down.

from Roger Ebert's review:

Many of them died under torture, including Jean Moulin, the original of Luc Jardie. Kessel: "Since he was no longer able to speak, one of the Gestapo chiefs, Klaus Barbie, handed him a piece of paper on which he had written, 'Are you Jean Moulins?' Jean Moulin's only reply was to take the pencil from Colonel Barbie and cross out the 's'."
