Seznec case: a new book explores the lead of Cadillacs and secret archives.
In *The Incomprehensible Enigma*, Bertrand Vilain presents the results of seven years of research on the ramifications of the Seznec case. Based in particular on archives from French counter-intelligence that returned from Moscow, he claims to have identified the network for purchasing Cadillacs intended for Soviet Russia that Pierre Quéméneur had been interested in before his disappearance in May 1923.
