D-99 by Horace Bowne Fyfe — Read

At the ninety-fifth floor, Westervelt left the public elevator for a private automatic one which he took four floors further. When he stepped out, the dark, lean youth faced an office entrance whose double, transparent doors bore the discreet legend: "Department 99."

He crossed the hall and entered. Waving at the little blonde in the switchboard cubby to the right of the doorway, he continued a few steps into the office beyond. Two secretaries looked up from the row of desks facing him, a third place being unoccupied. Behind them, long windows filtered the late afternoon light to a mellow tint.
