As a plaque shown below informs us, the author Maurice Leblanc (1864–1941) lived here at the Clos Lupin, Étretat, from 1915 until his death in 1914. In 1999 it was opened to the public by Leblanc's grand-daughter Florence. The tour is audio-guided (by Frence television's own Lupin, Georges Descrières) and is much more about Arsène Lupin and the mystery of L'Aiguille creuse than Maurice Leblanc himself: but then, look at the name of his house, where fiction takes over from reality. I let the photos tell the story, which ends with the treasure hidden in the needle, Lupin staring at it in the background.
