Arsène Lupin vs. Sherlock Holmes

Three persons seriously affected, Mr. Gerbois (475,000 francs of his lottery prize were stolen and his beloved daughter was kidnapped), the nephew of Baron d'Hautrec (whose uncle, a well-known and respected former ambassador, was murdered), and the Countess of Crozon (her valuable blue diamond was stolen) are disappointed because inspector Ganimard failed to capture the murderer and thief, the mysterious blonde lady, and her boss, the reckless Arsène Lupin. Despite the objections of the French detective, they hire Sherlock Holmes, who is determined to detain Arsène Lupin and the blonde lady, and return the jewel to the countess. While in the second part, at the request of a French nobleman and despite being threatened by Lupin of not intervening, Holmes investigates the strange theft of a Jewish lamp, discovering that things are not as obvious as they seem… So, who won the duel between Arsène Lupin and Sherlock Holmes?
