men who were willing to do the dirtiest kind of
work, in order that he might cause our downfall.

His honest, straightforward nature revolted at it. These two men were
spies, traitors. He wondered at their speaking so freely, that they
had not taken greater precaution to make sure no one was near. But the
room was peculiarly shaped, and it was difficult for them to see the
recess in which he sat, hidden as it was by the huge palm. To all
appearance the place was empty.

Again he acted on impulse. Forgetting the rights and wrongs of the
situation, he felt he must act. Looking through the fronds of the
palm, he saw that the two men were conversing eagerly. Behind him was
a door, but where it led he did not know. He must get out without
their being aware of his presence.

Silently he opened the door, and soon found himself in the domestic
portion of the little hotel. A waiter looked at him questioningly.
Bob held up his finger to command silence.

"Show me to the manager, at once," he said.

The waiter instinctively felt how much in earnest he was, and obeyed

and then they both entered silently.

The room was empty; the two men had gone.

"But can't we do anything?" asked Bob.

"What can we do, sir? If you were mistaken, then no harm is done. If
you were not, they must have seen you leave the room, and then made
their way out. I'll speak to the hall-porter. There are very few
people here to-night, and he will know how many people have gone out
during the last five minutes."

"Yes," the hall-porter declared a few seconds later, "two gentlemen
have just gone out in a hurry. They said they were late for an
appointment, and had to make haste."

"Did you recognise them?" asked the manager.

"I've seen them here once or twice before," was the porter's reply,
"but I know nothing about them."
