"Then this is my ultimatum. Either give me your word of honour to execute my commission or your dog will be destroyed by order of the court."

"You want me to transgress against the Defence of the Realm Act," rejoined Fordyce with rising temper. "I'll see you to blazes first. More than that, it will be my duty to report this conversation to the proper authorities."

"Do so, by all means," said Mindiggle suavely. "Do you think anyone would take your word against mine—a prominent municipal officer of this town? Remember, we have no witnesses. I would also point out that you have shown grave indiscretion (an unpardonable fault in a military or naval officer) by informing me of the date of departure of Submarine R19 and also her destination."

"It's my belief that you are tin-hatted," exclaimed Fordyce. "You mentioned those particulars: I did not."

"Until you told me, Mr. Fordyce, I was quite unaware of the number of your submarine or of your date of departure," reiterated Mindiggle. "I am afraid that in your agitation over the danger that threatens your pet you have lost control of your tongue."

"I've a good mind to lose control of my fist and to decorate your figurehead," thought Fordyce. "The fellow's tactics savour of blackmail or something suspiciously like it; but if I lay him out there'll be a most infernal row. Appearances will be against me."

"Don't be a fool," continued Mindiggle. "It's quite a simple matter. No risk about it, and nothing to prejudice the safety of the realm and all that sort of thing, don't you know. Now, then."

"I'll report the matter to the police," declared the Sub.

"Do so," was the calm reply. "Would the police believe such an accusation against a prominent member of the Watch Committee? Supposing—even supposing, mind—that they did take action and search my house. What would they find—nothing. Can't you realize that I hold the whip hand?"

"You can jolly well do what you like," answered the Sub.
