Fan Casting Sherlock Holmes VS Arsène Lupin

An anti-mahogany desk with a forgotten lottery was stolen from Parisian villa to the mathematician professor Gerbois. Lupine knows that he can't choose the win himself, so by fake the kidnapping of Gerbois' daughter Suzanne, he forces Gerbois to split the win in half with him. At the same time, Suzanne volunteered with Lupin's mysterious companion, La Dame Blonde, because she came to the conclusion that half the winnings were better than nothing. Soon after, a rare blue diamond is stolen from the Countess of Crozon's castle. Inspector Ganimard, who is investigating both cases, soon finds out that Arsena Lupine and the Blonde woman are also behind this crime. When his investigation does not lead to a successful conclusion, they ask the disabled for the help of the famous English detective Sherlock Holmes, who also arrives with his friend and companion Watson. Holmes's search is not very successful at first, and the detective falls into several of Lupin's traps. Eventually, however, he manages to reveal the identities of Blondie and Lupine in one of his houses. Lupine is arrested by Ganimard, but she secures the blonde's freedom with Sholmes by returning the diamond. However, after Holmes leaves, Lupine escapes and comes to the station to say goodbye to the departing Holmes.
