"Yes."
"Miss McDonald requested me to hand you this note unobserved. I have no knowledge of its contents."
Hamlin felt the flutter of the paper in his palm, and stood silent, clinging to it, as the other carelessly recrossed the room. She was looking toward him, but he made no motion to unfold the missive, until his eyes, searching the chairs, had located Mrs. Dupont. The very secret of delivery made him cautious, made him suspect it had to do with that woman. She was beside the band-stand, still conversing with the Major, apparently oblivious to any other presence, her face turned aside. Assured of this, he opened the paper, and glanced at the few hastily scribbled lines.
"I trust you, and you must believe I do not do this without cause. During the intermission be in the hotel parlor."
