Jack broke into a laugh, which suddenly changed into a quick exclamation of astonishment.

“Hark!” he cried.

“What’s the matter?” breathlessly from Raynor. “I didn’t hear anything.”

“You didn’t? You must be—there it is again.”

This time it was Raynor’s turn to start.

“I heard it all right then,” he exclaimed. “It was——”

“A woman screaming.”

“That’s what. Gracious, what’s the matter?”

“It’s off down that street there,” decided Jack, pointing a little distance ahead where a small street branched off the main thoroughfare and skirted a small, unlighted park. “Come on,” he shouted to Raynor, and was off.

“What are you going to do?” called Raynor.
