raid upon the Citrite factory.
Another factor entered. It happened that the marauders, thanks to their early start, had arrived while The
Shadow was still in conference with Alden. Having seen the parked cars, they were waiting in
concealment when the procession drove out.
Naturally, The Shadow hadn't been able to turn into the woods too soon; he was nearly a quarter of a
mile from the factory when he left the road. But Englemere and the men with him were beginning their
advance the moment the last taillight twinkled from sight. Unwittingly, they were putting to use the very
minutes that The Shadow required to make his return!
Stealthily, in clustered fashion, the tribe crept toward the main building. Professor Englemere formed the
central figure in the group of "keepers" that he had brought from his endowed home for apes. Only Griff
Perrick was able to restrain the ardent professor, with low-voiced warnings. Griff was piloting the throng,
for he knew the set-up that awaited.
They reached the heavy gate that afforded entry to the storeroom. Griff tried it, found it unlocked, and
pressed the others through, voicing his satisfaction in an undertone.
"Blink did a quick job," Griff complimented. "I've got to hand that to him. I kind of expected he wouldn't
have time to open the gate so soon."
Holding the others back, Griff turned to clamp the gate from the inside, remarking that it wouldn't do for
some watchman to find it open while making his rounds. Then, pressing ahead, Griff found the inner
passage and entered it, with Englemere.
The others had some difficulty squeezing through, and the reason for their clustering was explained. They
were huddled together because they were lugging Englemere's curious Vapor Gun, mounted on its stand.
Hardly had the last crooks moved into the passage before The Shadow glided into the grounds. The first
place he made for was the gate that Englemere's band had found unlocked. Trying the gate, The Shadow
discovered it to be secure, as he expected. The clamp on the inside gave it the effect of being locked.
Skirting the building, The Shadow reached the door that led up to the office. It was tightly locked, as
Dorset had left it. Looking upward, The Shadow could see the barred windows of the office, which
could be reached by first scaling the door. Those bars had an inviting look, for they were crosswise and
formed a ladder, offering access to the roof above.
Deftly, The Shadow moved upward, the slight wavy motion of his cloak giving the effect of oily smoke
rising in a slow cloud. So vague, that shape, against the gloom of the doorway and the window above,
that the living smoke seemed to dispel itself as it reached the roof edge. There, The Shadow had
flattened, and performed an inward roll that placed him upon the roof itself, away from any chance of
observation.
There was a soft laugh from The Shadow's hidden lips as he saw exactly what he wanted: a trapdoor in
the roof. It was fastened, of course, from the inside, as The Shadow learned when he tried it; but its slight
yield was proof that he could pry it loose within a dozen minutes.
If nothing else made it profitable, a trip down into the office would at least serve as a lesson for Alden
and the others, when they arrived in the morning to find that the place had been entered. So The Shadow
began his work in smooth but silent style.
It seemed a race against time, nothing more. Actually, it was a race against crime. For, while The
