“I don’t see how you ever struck such a blow,” he finally confessed. “But next time it will be my turn to strike—for her sake!”

Then he walked away, turning into Twenty-fifth Street and going toward Sixth Avenue.

“What do you make of it, anyhow?” asked Diamond.

“I don’t know just what to make of it,” acknowledged Frank, with a frown on his handsome face. “It’s very unpleasant, and I am completely puzzled.”

The men who had gathered about were staring at them, and they moved away after the man with whom Merry had had the encounter.

“If I could recall the name of that girl, I’d feel better,” Frank declared. “I don’t remember when I’ve ever forgotten a name before this. But I cannot even remember under what circumstances we previously met, though I am certain there was something very striking about it. It is possible I may never have known her name, and still——”

“Still, she knew yours.”

“Yes.”

“The man—do you remember him?”

Merry shook his head.
