"An assassination," murmured Gaston, not daring to cry out, for fear of compromising Helene; "cowards!"

"We are betrayed, monsieur," said Dubois, rolling up Gaston's cloak and coat, and putting them under his arm; "we shall meet again to-morrow, no doubt."

And he ran toward the hotel, while they shut up Gaston in the lower room.

Dubois ran up the staircase and into his room, where he opened the precious pocket-book. He found in one pocket a broken coin and a man's name.
