They bowed to each other as if about to part. But, at that moment, they heard a sound of horses’ feet, accompanied by a clinking of steel. It was the gendarmes. The two men were obliged to draw back against the embankment, amongst the brushes, to avoid the horses. The gendarmes passed by, but, as they followed each other at a considerable distance, they were several minutes in doing so. And Lupin was thinking:

“It all depends on that question: has he recognized me? If so, he will probably take advantage of the opportunity. It is a trying situation.”

When the last horseman had passed, Sherlock Holmes stepped forth and brushed the dust from his clothes. Then, for a moment, he and Arsène Lupin gazed at each other; and, if a person could have seen them at that moment, it would have been an interesting sight, and memorable as the first meeting of two remarkable men, so strange, so powerfully equipped, both of superior quality, and destined by fate, through their peculiar attributes, to hurl themselves one at the other like two equal forces that nature opposes, one against the other, in the realms of space.

Then the Englishman said: “Thank you, monsieur.”

“You are quite welcome, replied Arsène Lupin.”

They parted. Lupin went toward the railway station, and Sherlock Holmes continued on his way to the castle.

The local officers had given up the investigation after several hours of fruitless efforts, and the people at the castle were awaiting the arrival of the English detective with a lively curiosity. At first sight, they were a little disappointed on account of his commonplace appearance, which differed so greatly from the pictures they had formed of him in their own minds. He did not in any way resemble the romantic hero, the mysterious and diabolical personage that the name of Sherlock Holmes had evoked in their imaginations. However, Mon. Devanne exclaimed with much gusto:

“Ah! monsieur, you are here! I am delighted to see you. It is a long-deferred pleasure. Really, I scarcely regret what has happened, since it affords me the opportunity to meet you. But, how did you come?”

“By the train.”

“But I sent my automobile to meet you at the station.”
