The ending of his life is not clear, because the author, Maurice Leblanc, was dead in 1941 before completing "Le Dernier Amour d'Arsène Lupin" (), the 21st volume of the series. Leblanc was presented the French Legion of Honour award for inspiring the patriotism and pride of French people by his Lupin series. He bought a house in Etretat and named it "Le Clos Lupin" (the vacation of lupin), which is still famous as a tourist attraction.
