Monsieur Frederic Larsan, who has seen me at work at the Glandier, can tell you with what care I studied this case.

I found myself compelled to differ with him in arresting Monsieur Robert Darzac, who is innocent.

Monsieur Larsan knows of my good faith and knows that some importance may be attached to my discoveries, which have often corroborated his own." Frederic Larsan said: "Monsieur President, it will be interesting to hear Monsieur Joseph Rouletabille, especially as he differs from me." A murmur of approbation greeted the detective's speech.

He was a good sportsman and accepted the challenge.

The struggle between the two promised to be exciting.
As the President remained silent, Frederic Larsan continued: "We agree that the murderer of the keeper was the assailant of Mademoiselle Stangerson; but as we are not agreed as to how the murderer escaped, I am curious to hear Monsieur Rouletabille's explanation." "I have no doubt you are," said my friend.
General laughter followed this remark.
