As he sauntered across the little square his gaze suddenly shifted to a second-story window above the gun-shop.
The interesting young woman had cautiously pushed open one of the shutters and was peering down upon the trio of red-coated guardsmen.
Almost at the same instant her quick, eager gaze fell upon the tall American, now quite close to the horsemen.

He saw her dark eyes expand as if with surprise.

The next instant he caught his breath and almost stopped in his tracks.
A shy, impulsive smile played about her red lips for a second, lighting up the delicate face with a radiance that amazed him.

Then the shutter was closed gently, quickly.

His first feeling of elation was followed instantly by the disquieting impression that it was a mocking smile of amusement and not one of inviting friendliness.
