The Billions of Arsène Lupin is a detective novel by Maurice Leblanc about gentleman thief Arsène Lupin. The novel appeared in 29 daily serials, illustrated by Jean Oberle in Auto from 10 January to 11 February 1939, then published in volume 16 in Hachette (Collection "The Enigma" No. 13) in November 1941, with illustrations by André Pécoud. The Hachette edition of 1941, a story that has not been written, in fact, beyond 1939, is the only edition in 1987 before insertion of this ultimate story of Arsène Lupin in the collection of Francis Lacassin (Volume 4, published in 1987). Thus, there are two posthumous editions. It is likely that illness and death had prevented the author of completing this novel; the family has refused for 46 years to a second issue, to respect the memory of the novelist. "If not adhere to this rule is to avoid compromising the completeness of our edition" 2. The Hachette edition 1941 is incomplete: one of the 29 operas "L'Auto", n ° 23 of February 3, 1939, was omitted by mistake. Error repeated in the reissue Robert Laffont 1987: Volume 4 of "Mouthpieces" collection is similarly amputated.
