The woman, plainly unconscious that she was followed, went on until she reached Twenty-first Street, when she was stopped by Grammery Park.

She turned to the right, or toward the west, and went around the park to Twentieth Street, and so down to Irving place.

Into this short street she turned, continuing on to Seventeenth Street.

“Hide!” cried Chick, just as she reached the corner, springing over the fence into a courtyard.

Patsy obeyed immediately and the lineman caught on quickly enough to prevent himself from being seen.

As Chick had anticipated, the woman had stood still on the corner and looked back.

As no one was to be seen, she was apparently satisfied that she was unobserved, for she turned to the left and went out of sight.

The three came from their hiding places, and, at Chick’s suggestion, Patsy stole up to the corner, peering around it.

He signaled for Chick to come, and dashed across Seventeenth Street.

The woman was pursuing her way toward Third Avenue on the upper side of Seventeenth Street.
