Many people had now gathered on the banks of the river, and Ganimard and his men followed the boat as it slowly floated down the stream. Lupin’s capture was a mathematical certainty.

“Confess, old fellow,” said Lupin, turning to the Englishman, “that you would not exchange your present position for all the gold in the Transvaal! You are now in the first row of the orchestra chairs! But, in the first place, we must have the prologue ... after which we can leap, at one bound, to the fifth act of the drama, which will represent the capture or escape of Arsène Lupin. Therefore, I am going to ask you a plain question, to which I request a plain answer—a simple yes or no. Will you renounce this affair? At present I can repair the damage you have done; later it will be beyond my power. Is it a bargain?”

“No.”

Lupin’s face showed his disappointment and annoyance. He continued:

“I insist. More for your sake than my own, I insist, because I am certain you will be the first to regret your intervention. For the last time, yes or no?”

“No.”

Lupin stooped down, removed one of the boards in the bottom of the boat, and, for some minutes, was engaged in a work the nature of which Sholmes could not discern. Then he arose, seated himself beside the Englishman, and said:

“I believe, monsieur, that we came to the river to-day for the same purpose: to recover the object which Bresson threw away. For my part I had invited a few friends to join me here, and I was on the point of making an examination of the bed of the river when my friends announced your approach. I confess that the news did not surprise me, as I have been notified every hour concerning the progress of your investigation. That was an easy matter. Whenever anything occurred in the rue Murillo that might interest me, simply a ring on the telephone and I was informed.”

He stopped. The board that he had displaced in the bottom of the boat was rising and water was working into the boat all around it.

“The deuce! I didn’t know how to fix it. I was afraid this old boat would leak. You are not afraid, monsieur?”
