With a grunt of rage he hit the other square between the eyes, and the clerk collapsed in a huddled heap behind the counter with the bell still unrung.For a few moments the big man stood motionless, listening intently. From upstairs came the faint tapping of a typewriter; from outside the usual street noises of London came softly through the two closed doors. Then, with an agility remarkable in one so big, he vaulted the counter and inspected the recumbent assistant with a professional eye. ”
