"I've spent over a million dollars, and now I've got a boat that can see under water and fight under water and do a lot of other fancy tricks."

Mr. Llewellyn John sprang to his feet.

"You have. Tell me, where is it? This is wonderful, wonderful! It takes us a year forward."

"It's on the St. Lawrence River, just below Quebec," explained John Dene.

"And how long will it take to construct say a hundred?" asked Mr.

Llewellyn John eagerly, dropping back into his chair.

"Longer than any of us are going to live," replied John Dene grimly.

Mr. Llewellyn John looked at his visitor in surprise. Sir Lyster and the Admiral exchanged meaning glances. The Prime Minister was experiencing what in Toronto were known as "John's snags."

"But if you've made one----" began Mr. Llewellyn John.

"There's only going to be one," announced John Dene grimly.

"But----"

"You can but like a he-goat," announced John Dene, "still there'll be only our _Destroyer_."

Sir Lyster smiled inwardly. His bruised dignity was recovering at the sight of the surprised look on the face of the Prime Minister at John Dene's comparison.

"Perhaps Mr. Dene will explain to us the difficulties," insinuated Sir Lyster.

"Sure," said John Dene; then turning to Admiral Heyworth, "What would happen if Germany got a submarine that could see and do fancy stunts?"

he demanded.

"It might embarra.s.s----" began the Admiral.

"Shucks!" cried John Dene, "it would bust us up. What about the American transports, food-ships, munitions and the rest of it. They'd be attacked all along the three thousand miles route, and would go down like neck-oil on a permit night. You get me?"

Suddenly Mr. Llewellyn John struck the table with his fist.

"You're right, Mr. Dene," he cried; "they might capture one and copy it. You remember the Gothas," he added, turning to Sir Lyster.

"Sure," was John Dene's laconic reply.

"But how can we be sure they will not capture the _Destroyer_?"

enquired Sir Lyster.

"Because there'll be John Dene and a hundred-weight of high-explosive on board," said John Dene drily as he chewed at the end of his cigar.

"Then you propose----" began Admiral Heyworth.

"I'll put you wise. This is my offer. I'm willing to send U-boats to merry h.e.l.l; but only on my own terms. I won't take a cent for my boat or anything else. It's my funeral. The _Destroyer_ is now in Canada, with German spies buzzing around like flies over a dead rat. If you agree, I'll cable to my boys to bring the _Destroyer_, and it won't be done without some fancy shooting, I take it! You," turning to Admiral Heyworth, "will appoint an officer, two if you like, to come aboard and count the bag. I'll supply the crew, and you'll give me a commander's commission in the Navy. Now, is it a deal?"

"But----" began Sir Lyster.

"You make me tired," said John Dene wearily. "Is it or is it not a deal?" he enquired of Mr. Llewellyn John.

With an effort the Prime Minister seemed to gather himself together.

He found the pace a little breathless, even for him.

"I think it might be arranged, Grayne," he said tactfully. "Mr. Dene knows his own invention and we might enrol his crew in the Navy; what do you think?" Mr. Llewellyn John abounded in tact.

"I take it that you understand navigation, Mr. Dene?" ventured the Admiral.

"Sure," was the reply. "You come a trip with me, and I'll show you navigation that'll make your hair stand on end. Sorry," he added a moment after, observing that Admiral Heyworth was almost aggressively bald.

"That's all right," laughed the Admiral; "they call me the coot."

"Well, is it a deal?" demanded John Dene, rising.

"It is," said Mr. Llewellyn John, "and a splendid deal for the British Empire, Mr. Dene," he added, holding out his hand. "It's a great privilege to meet a patriot such as you. Sir Lyster and Admiral Heyworth will settle all details to your entire satisfaction."

"If they do for me, I want you to give the command to Blake, then to Quinton, and so on, only to my own boys; is that agreed?"

"Do for you?" queried Mr. Llewellyn John.

"Huns, they're after me every hour of the day. There was a little chap even in your own building."

"We really must intern these Germans----" began Mr. Llewellyn John.

"You're barking up the wrong tree, over here," said John Dene with conviction. "You think a German spy's got a square head and says 'Ach himmel' and 'Ja wohl' on street-cars. It's the neutrals mostly, and sometimes the British," he added under his breath.

"In any case you will, I am sure, find that Sir Lyster will do whatever you want," said Mr. Llewellyn John as they walked towards the door.

For the second time that morning John Dene smiled as he left No. 110, Downing Street, with Sir Lyster and Admiral Heyworth, whilst Mr.

Llewellyn John rang up the chief of Department Z.

CHAPTER II

JOHN DENE'S WAY

As Sir Lyster entered Mr. Blair's room, accompanied by John Dene and Admiral Heyworth, he was informed that Sir Bridgman North, the First Sea Lord, was anxious to see him.

"Ask him if he can step over now, Blair," said Sir Lyster, and the three men pa.s.sed into the First Lord's room. Two minutes later Sir Bridgman North entered, and Sir Lyster introduced John Dene.

For a moment the two men eyed one another in mutual apprais.e.m.e.nt; the big, bluff Sea Lord, with his humorous blue eyes and ready laugh, and the keen, heavy-featured Canadian, as suspicious of a gold band as of a pickpocket.

"Pleased to meet you," said John Dene perfunctorily, as they shook hands. "Now you'd better give me a chance to work off my music;" and with that he seated himself.

Sir Bridgman exchanged an amused glance with Admiral Heyworth, as they too found chairs.
