"Don't get the idea that we are going to do any running about in
Paris," Dave warned his chum.

"Not even if we have some idle time there?"

"Not even then," Dave answered. "I am very sure that neither the
Admiral nor the Ambassador would wish us to show ourselves much at the
French capital. We might thereby attract the attention of spies."

"That is true," agreed Lieutenant Totten.

Business being now attended to, Dave and Dan had time to finish
dressing comfortably. Then followed a period of waiting. Later the
hotel clerk was asked to summon an automobile. In this the Paris-bound
party, including Runkle, left the hotel, Totten accompanying them.

No sooner, however, had the American party left the hotel than an
Italian, crouching in the shadow of a building further along on the
same block, whispered to his companion:

"Telephone Signor Dalny for instructions."

Within three minutes a second automobile rolled up to the hotel.

"To the railway station first, on the chance of finding the Americans
there," the spy called to the driver.

Dave's party did not have long to wait at the station. Totten remained

"There's that spy fellow getting on the running-board further down the
train, sir," whispered Runkle.

"I expected him," answered Dave dryly.

"Would you like to lose him, sir?"

"Off the train altogether, do you mean, Runkle?"

"Yes, sir."

"Can you put him off without hurting him?"

"I think I can get him off, sir, without even scraping one of his
knuckles."

"You're at liberty to try, Runkle, if you are sure you won't injure
the man."

As the guard came along, locking the doors, Runkle leaped down to the
ground.

"Help, Mr. Totten, help!" called the seaman in a low voice that none
the less reached the ears of the departing lieutenant.

Then Runkle moved directly up to the spy leering into his face and
making insulting signs that
