"I am not even going to ask you to do it," retorted the young woman. "And now our interview is over. I am going to leave you, and I shall not see you again. I——-"

"Going to leave me, are you?" leered her tormentor. He stepped forward, holding out his hand, as though to seize the young woman's wrist, but she alertly eluded him.

"If you try again to touch me, or if you attempt to follow me," warned the young woman, "I shall appeal for assistance."

So absorbed were the disputants in their quarrel that neither had noticed Darrin, standing on the corner.

The tormentor's face flushed, then went white, "Make your appeal," he dared, "and see what happens!"

Again he attempted to take the girl by the wrist.

"Can I be of service, madam?" inquired Darrin, as he strode toward them.

Like a flash, the annoyer wheeled upon Darrin, his eyes flashing dangerously.

"Young man," he warned, threateningly, "the best thing you can possibly do will be to make yourself scarce as quickly as possible. As for this young woman——-"

The tormentor moved a step nearer to the young woman, whose face had turned very pale.
