The Crystal Stopper
 During a burglary at the home of Deputy Daubrecq a crime is committed and two accomplices of Arsène Lupin were arrested by the police. One is guilty of the crime, the other innocent but both will be sentenced to death. Lupin seeks to deliver the victim of a miscarriage of justice, but struggles against Deputy Daubrecq's ruthless blackmailer, who has an incriminating document hidden in a crystal stopper. http://www.gutenberg.org/ebooks/1563 fr:Le Bouchon de cristal ja:水晶の栓 pl:Kryształowy korek
