The officer drew himself up:
“Oh, I can’t agree to that, you know!”
“Very well, then give me your word of honor that you’ll keep a secret which doesn’t belong to you. After which, we’ll say good-night and go our own ways. I’ll do the boarding alone and you can go back to your own business. Observe, however, that I am not insisting on an immediate reply. You have plenty of time to reflect and to take the decision which your interest, honor and conscience may dictate to you. For my part, excuse me, but you know my weakness: when circumstances give me a little spare time, I take advantage of it to go to sleep. Carpe somnum, as the poet says. Good-night, captain.”
And, without another word, Don Luis wrapped himself in his great-coat, sprang into the boat and lay down.
Patrice had had to make a violent effort to restrain his anger. Don Luis’ calm, ironic tone and well-bred, bantering voice got on his nerves all the more because he felt the influence of that strange man and fully recognized that he was incapable of acting without his assistance. Besides, he could not forget that Don Luis had saved his life and Coralie’s.
The hours slipped by. The adventurer slumbered peacefully in the cool night air. Patrice hesitated what to do, seeking for some plan of conduct which would enable him to get at Siméon and rid himself of that implacable adversary and at the same time to prevent Don Luis from laying hands on the enormous treasure. He was dismayed at the thought of being his accomplice. And yet, when the first throbs of the motor were heard in the distance and when Don Luis awoke, Patrice was by his side, ready for action.
They did not exchange a word. A village-clock struck ten. The Belle Hélène was coming towards them.
Patrice felt his excitement increase. The Belle Hélène meant Siméon’s capture, the recovery of the millions, Coralie out of danger, the end of that most hideous nightmare and the total extinction of Essarès’ handiwork. The engine was throbbing nearer and nearer. Its loud and regular beat sounded wide over the motionless Seine. Don Luis had taken the sculls and was pulling hard for the middle of the river. And suddenly they saw in the distance a black mass looming up in the white moonlight. Twelve or fifteen more minutes passed and the Belle Hélène was before them.
“Shall I lend you a hand?” whispered Patrice. “It looks as if you had the current against you and as if you had a difficulty in getting along.”
“Not the least difficulty,” said Don Luis; and he began to hum a tune.
