She was about to turn into the house to summon help when she heard a stir in the shrubbery in quite another part of the garden, and in a moment the stooping figure of a man moved swiftly toward the pergola.
Shirley stood quite still, watching and listening.

The sound of steps in the pergola reached her again, then the rush of flight, and out in the garden a flying figure darted in and out among the walks.

For several minutes two dark figures played at vigorous hide-and-seek.

Occasionally gravel crunched underfoot and shrubbery snapped back with a sharp swish where it was caught and held for support at corners.

Pursued and pursuer were alike silent; the scene was like a pantomime.
Then the tables seemed to be turned; the bulkier figure of the pursuer was now in flight; and Shirley lost both for a moment, but immediately a dark form rose at the wall; she heard the scratch of feet upon the brick surface as a man gained the top, turned and lifted his arm as though aiming a weapon.
Then a dark object, hurled through the air, struck him squarely in the face and he tumbled over the wall, and Shirley heard him crash through the hedge of the neighboring estate, then all was quiet again.
The game of hide-and-seek in the garden and the scramble over the wall had consumed only two or three minutes, and Shirley now waited, her eyes bent upon the darkly-outlined pergola for some manifestation from the remaining intruder.
