the motor-cars at
that point. He became aware of her emergence with a start, he ceased to
lean and became observant.

He was one of those men whose face suggests the word "muzzle," with an
erect combative nose and a forward slant of the body from the rather
inturned feet. He wore an observant bowler hat a little too small for
him, and there is something about the tail of his jacket--as though he
had been docked.

She passed at a stride to the acceptance of Mr. Brumley's hitherto
incredible suspicion. Her pulses quickened. It came into her head to see
how far this man would go in following her. She went on demurely down
the hill leaving him quite unaware that she had seen him.

She was amazed, and after her first belief incredulous again. Could

idea of Sir Isaac. Watched by a detective! This then was the completion
of the conditional freedom she had won by smashing that window. She
might have known....

She was astonished and indignant but not nearly so entirely indignant as
a noble heroine should have been. She was certainly not nearly so
queenly as Mrs. Sawbridge would have shown herself under such
circumstances. It may have been due to some plebeian strain in her
father's blood that over and above her proper indignation she was
extremely interested. She wanted to know what manner of man it was whose
nose was just appearing above the window edge of the taxi-cab behind. In
her inexperienced inattention she had never yet thought it was possible
that men could be hired to follow women.

She sat a little forward, thinking.

How far would he follow her and was it p
