"May I come to see you to-night?" he asked, trying not to stammer, and hoping his ears were not as red as they felt. "There's a nice band concert in Prospect Park and I thought——"

Martha Ritter cocked her head to one side and smiled mysteriously.

"I'm sorry, Mr. Epps," she said coolly, "but I have an engagement."

"You—have—an—engagement?" He repeated the words as if they were a prison sentence.

"Yes."

"Where?"

"Oh, it's a masquerade." She smiled, her head on one side.

"Whom are you going with?" he blurted; he was trembling.

"That would be telling," she laughed. "Well, good night, Mr. Epps. I must hurry home and get my costume on. I'm going as a gypsy."

And she disappeared into the maw of the Subway.
