Rh see everything—the chamber is so small and scantily furnished, and all was locked behind in the pavilion."

I ventured on a hypothesis:—

"Perhaps he got away with the mattress—in the mattress!—Anything is possible, in the face of such a mystery! In their distress of mind Monsieur Stangerson and the concierge may not have noticed they were bearing a double weight; especially if the concierge were an accomplice! I throw out this hypothesis for what it is worth, but it explains many things,—and particularly the fact that neither the laboratory nor the vestibule bear any traces of the footmarks found in the room. If, in carrying Mademoiselle on the mattress from the laboratory of the château, they rested for a moment, there might have been an opportunity for the man in it to escape."

"And then?" asked Rouletabille, deliberately laughing under the bed.

I felt rather vexed and replied:—

"I don't know,—but anything appears possible"—

"The examining magistrate had the same idea, monsieur," said Daddy Jacques, "and he carefully examined the mattress. He was obliged to laugh at the idea, monsieur, as your friend is doing now,—for whoever heard of a mattress having a double bottom?"

I was myself obliged to laugh, on seeing that what I had said was absurd; but in an affair like this one hardly knows where an absurdity begins or ends.
