Clyde knew the dynamic personality of Doctor Palermo, and he felt sure that the man would make a desperate effort to escape from The Shadow’s net.

The situation was dramatic. This was the first evening that the men had watched the entrance of the Marimba Apartments. Clyde had a suspicion that perhaps The Shadow had been on watch the night before. Perhaps the vigil would continue for many nights.

Palermo must have caution as well as wisdom. But if he were waiting for The Shadow to betray his plans, Palermo would wait in vain. For there was no way in which he could detect the watchers hidden across the street.

Clyde and Harry were in an apartment of an older building. The entrance was a street beyond. They did not come within a block of the Marimba Apartments when they made their entry.

“What is Burbank like?” asked Clyde. He was wondering if Doctor Palermo would suspect the new elevator man.

“A quiet chap, as I said before,” answered Harry. “He’s the ideal man for this job. He is a jack of all trades. Operating an elevator is right in his line. He fits the part to perfection.”

“Palermo won’t suspect him?”

“No one would suspect Burbank. The Shadow uses him on very rare occasions. I have never talked with Burbank; in fact, I have scarcely ever seen him.

“The instructions that I received today explained Burbank’s part in this work. That was all that was said about him.”

A LIMOUSINE drew up in front of the Marimba. Two ladies came out of the apartment house and drove away.
