On coming off deck duty at eight bells, midnight, Lieutenant Totten was instructed to order a launch alongside. Then, with the bulky envelope in an inner pocket, and accompanied by Seaman Runkle, Totten went over the side.

A few minutes later the launch delivered them at the mole, then glided out into the bay.

"I hope we shan't run into a gang of hoodlums again," said the sailorman respectfully.

"I have my revolver with me," smiled the lieutenant. "The Italian police would feel grateful if I sank its six bullets into six bravos of Naples."

CHAPTER XIV

DAN HAS VERY "COLD FEET"

Rap-tap!

That sound brought Dave Darrin out of a sound sleep. Dan slumbered on.

"Who's there at this hour of the night?" asked Dave, through the door, in the best Italian he could muster.

"From the 'Hudson,'" came the answer, in a voice so low that Dave did not recognize it.

"One minute, then."

Dave slipped back, shaking his chum to rouse him, then drew the curtains around Dalzell's bed.

In record time Dave drew on his own shirt, slipped into trousers, put on collar, cuffs and tie, and followed this with coat and vest.

Then he stepped to the door, opening it. Repressing his natural cry of astonishment, Dave silently admitted his visitors, next closed and locked the door.

"Orders from the Admiral," said Lieutenant Totten, in an undertone, and pa.s.sed over the envelope.

Stepping under the light which he had hastily turned on, Darrin read his orders.

"Read this, Dan," said Dave, pa.s.sing the letter of instructions to his chum, who was now also fully dressed. "Then I will read it once more, after which we will burn it."

"Suits me," commented Dan, when he had finished and was pa.s.sing back the letter. "I've always wanted to see Paris."

"You won't see much of it this time," smiled Ensign Dave. "This is business, and nothing else."

Then Dave tore the letter into strips. Taking these to the open fireplace he set fire to them. All three officers watched until the letter had been completely burned.

"And now," Dave continued, "I will mix this charred paper thoroughly with the ashes that, fortunately, are left in the grate."

When he had finished, the mixing had been done so well that they would be keen eyes, indeed, that could note the presence of minute particles of burned paper in the grate's contents. His next act was to telephone the hotel clerk to send up a time-table.

"We have plenty of time, yet," smiled Darrin, glancing at his watch, after he had finished consulting the time-table. "It won't be the height of comfort to travel to Paris without baggage. However, when we get there we can buy anything that we may need."

"It will be great to shop in Paris," cried Dan, his eyes gleaming.

"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 Amba.s.sador 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 with them to the last, however, that he might be able to report a safe start to the Admiral.

"Don't look, sir, but coming up behind you, I am certain, is a fellow I saw on the street outside the hotel just before we started,"

reported Seaman Runkle.

"Then we are being trailed," Dave said.

Not until the time came for starting did Lieutenant Totten shake hands hurriedly with his brother officers and leave them, though he still stood near the train.

Dave and Dan sprang into their compartment in one of the cars, Able Seaman Runkle following more slowly.

"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 sc.r.a.ping 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.
