Ganimard is not one of those mighty detectives whose proceedings form a school, as it were, and whose names will always remain inscribed on the judicial annals of Europe. He lacks the flashes of genius that illumine a Dupin, a Lecoq or a Holmlock Shears. But he possesses first-rate average qualities: perspicacity, sagacity, perseverance and even a certain amount of intuition. His greatest merit lies in the fact that he is absolutely independent of outside influences. Short of a kind of fascination which Arsène Lupin wields over him, he works without allowing himself to be biased or disturbed.

At any rate, the part which he played that morning did not lack brilliancy and his assistance was of the sort which a magistrate is able to appreciate.

"To start with," he began, "I will ask Charles here to be very definite on one point: were all the objects which, on the first occasion, he saw upset or disturbed put back, on the second, exactly in their usual places?"

"Exactly."

"It is obvious, therefore, that they can only have been put back by a person to whom the place of each of those objects was familiar."

The remark impressed the bystanders. Ganimard resumed:

"Another question, Mr. Charles.... You were woke by a ring.... Who was it, according to you, that called you?"

"Monsieur le baron, of course."

"Very well. But at what moment do you take it that he rang?"
