, but I, too," with Gaston boastfulness, "can aspire to a little
cleverness."

"A great deal," said Mr. Heatherbloom, the while his brain worked
rapidly. Betty Dalrymple must have paid the youth well for serving her
thus far. Thrift, as well as sentiment, seemed to shine from Francois'
eloquent dark eyes. Could he be induced to espouse her cause yet
further?

"Monsieur must not think I would prove disloyal to his excellency, my
employer," spoke up the youth as if reading what had been passing
through the other's mind. "There could be no harm in a mere inquiry as
to monsieur's state of health."

"None at all," assented the prisoner quickly. "Though"--a sudden
inspiration came to Mr. Heatherbloom--"contingencies may arise when one
can best serve those who employ him by secretly opposing them."

"I don't understand, Monsieur," said Francois cautiously.

"The prince is a madman. By incurring the enmity of his Imperial Master
he would rush on to his own destruction. Suppose by this misalliance,
the very map of Europe itself were destined to be changed?"

The words sounded portentous, and Francois stared. He had imagination.
The beautiful American girl had told him that this man before him was a
great and daring detective. He spoke now even as an emissary of the czar

Francois mentioned an island.

"When do we get there?"

"We are near it to-night but on account of the rocks and reefs, I heard
the captain say we would slow down, so as not to enter the harbor until
daybreak."

Daybreak! And then? Mr. Heatherbloom closed his eyes; when he again
opened them they revealed none of the poignant emotion that had swept
over him. "What time is it now?"

"About ten."

"My jailer--the third officer, you say--visits this cell once every
night. Do you know what time he comes?"

"I shouldn't be here, Monsieur, at this moment, if I didn't know that.
He comes in an hour, after his watch is over, with the bread and
water--monsieur's frugal fare. And now"--those apprehensions,
momentarily dulled by wonderment seemed returning to Francois--"I will
bid monsieur--"

"Stay! One moment!" Mr. Heatherbloom's accents were feverish,
commanding. "You must--in the name of the czar!--for the pr
