Arsène Lupin vs. Herlock Sholmes is a collection of two adventures of Arsène Lupin, written by Maurice Leblanc.
These adventures feature a match of wits between Lupin and Herlock Sholmes, a transparent reference to Sherlock Holmes, the hero of Conan Doyle's detective stories. It follows the appearance of Arsène Lupin, Gentleman Burglar, in which Sherlock Holmes also makes an appearance in "Sherlock Holmes Arrives Too Late". The collection was translated twice into English, as Arsène Lupin versus Herlock Sholmes in the U.S. (1910, by George Morehead), and as Arsène Lupin versus Holmlock Shears in the UK (1910, by Alexander Teixeira de Mattos, printed as The Blonde Lady in the U.S.).
The first story, "The Blonde Lady", opens with the purchase of an antique desk by a mathematics professor. The desk is subsequently stolen, as it turns out, by Arsène Lupin.
