I recently found these comments from Jean-Pierre Alaux and Noël Balen about their inspiration for Late Harvest Havoc.
There is a story behind this particular Benjamin Cooker adventure. We were in Alsace researching and already had a specific plot in mind. However, when we arrived in Colmar, a story was plastered all over the front page of the local papers. The backdrop was the Alsatian vineyard, and some madman was attacking the vinestock at night, destroying the best vines. It was a local chainsaw massacre or sorts. We didn't need much pushing to change our initial story idea. Then we spent some time in Colmar reworking the case into the story that became Late Harvest Havoc. This wasn't the first time that a local news story inspired us, but it was by far the most original one.
