as long as Mr. Graham had stated. As she looked back over
the years she was able to recall man after man whom she had flattered
and lured by the witchery of her eyes. Secret after secret she had
coaxed from men entrusted with guarding such mysteries. The rewards of
the work had kept M. Lemaire and herself both bountifully supplied with
money by the foreign governments that they had served as spies. Most
men whom she had tried to win into her service the young Russian woman
had found easy enough victims. But now, here was a sixteen-year-old
boy laughing at her attempts at "cleverness."

"I was wrong to think Jack Benson a fool," she said to herself, angrily.
"He is far more clever than the men I have met. I can do nothing with
him. I must turn him over to Lemaire--to see if that prince of spies,
as he has often been called, can find the flaw in this submarine boy's
armor."

With that Mlle. Nadiboff leaned forward, murmuring a few words to the
chauffeur, who nodded slightly. Then the young woman leaned back,
turning a smiling, friendly but no longer coaxing face to Jack Benson.

"If I have amused you," she smiled, "I am glad. We will say that much
and forget the rest, eh, Captain Benson."

"I am glad to agree to anything that will please you," responded the boy,
gravely.

Mlle. Nadiboff shot a covert look at his face, then decided to say
nothing. She began to have a suspicion that this sixteen-year-old boy
was far more clever than she, despite all her years of strange
experiences.

A mile further along the automobile branched off the main road, running
down a shaded lane at much reduced speed.

"What is this--some short cut back to the beach?" asked Jack, trying
to conceal his astonishment.

"Yes," replied the young Russian, falsely.

Soon the big car stopped. The chauffeur thrust a whistle between his
lips, blowing a trilling blast.

Jack Benson changed color somewhat. This sounded suspicious--a signal
in the woods. It was doubly suspicious after the hints that Mr. Graham
had given the young submarine captain.

"Do not jump--do not be afraid," laughed Mlle. Nadiboff, rather
maliciously. "Nothing in the way of danger threatens."

Almost immediately the chug-chug of another auto was heard, just ahead
up the narrow road. Then into sight glided a small runabout, which sat
M. Lemaire, all by himself. That Frenchman stopped his car, next waving
one hand gayly to those in the larger car.

Then,
