The man who had been in the room made for the door. His square-shouldered form showed
as he opened the barrier. Then the door closed and the later arrival remained alone. The
watch had been changed.
These two men were agents of The Shadow. Harry Vincent, an experienced operative, had
just replaced Cliff Marsland. Harry had been longer in The Shadow's service than had Cliff;
the latter, however, had the advantage of being in close contact with the affairs of the
underworld.
HARRY VINCENT, posted here to watch Room 850, had been the first to spy the occupants
across the hall—one, a hard-faced fellow who had taken Room 850 under the name of
Bates; the other, a suave individual who was not registered. It was Cliff Marsland, however,
who had peered through the transom to identify "Bates" as "Pug" Halfin, a one-time
mobleader well known in the badlands of New York.
These facts had been submitted in reports to Rutledge Mann. While awaiting The Shadow's
orders, Cliff and Harry had continued their relayed vigil. Both had worked from under cover;
neither had been observed by either Pug Halfin or his unknown companion.
Seating himself in the corner of the darkened room, Harry put in a telephone call. This was
to Burbank, The Shadow's contact man. Harry was terse and non-committal in his
statements. He was merely reporting that he was on duty; and doing it in a fashion that
indicated nothing more than a call to a friend. It was Cliff, now outside the hotel, who would
give Burbank a more detailed report.
The situation, however, presented nothing new. Harry and Cliff had been on watch for three
nights; since Cliff's early identification of Pug Halfin, nothing new had developed.
While Harry Vincent was engaged in his call to Burbank, a peculiar phenomenon took place.
Without Harry noticing it, the door of the room opened inward. No light came from the
corridor, for a blackened shape filled the opened portion of the doorway. It was not until he
arose from his chair that Harry Vincent realized he was not alone. The token of another
presence came in a whispered tone.
The Shadow!
Harry was startled by the unexpected arrival of his chief. He could see no one in the
darkness. That, however, was not unusual. Enshrouded by gloom, The Shadow had a
marked ability for rendering himself invisible.
"Remain on duty," came the whispered order. "Timed report. Zero."
Nodding in the darkness, Harry drew a watch from his pocket. He pressed the stem and
held it in readiness, awaiting the next word.
"Set," came The Shadow's whisper.
A slight click from Harry's hand was answered by a similar sound from the spot where The
Shadow stood. Two stop-watches, set at the same beginning, were ticking off identical
seconds.
Something swished softly in the darkness. Harry saw the door move inward. He noted
blocking blackness; then the door was closed. The Shadow had started forth. Harry drew a
chair to the door and stood upon it, keeping watch through the transom. There was no sign
of The Shadow. Already, the master sleuth had passed along the corridor, beyond the door
of Room 850.
