Rummings took careful aim and squeezed the trigger. A large hole appeared in the curtain glazing surrounding the building and the executive staggered sideways.
After pumping a few more bullets into the dying man’s body, Rummings abandoned the rifle, ran back to the exit door, paused long enough to strip off the coveralls and then raced down the stairs. Once in the corridor, he deliberately slowed himself down, calmly called a lift and went down to the ground floor again. "
