“None, sir—so far as I know. Domestic crime isn’t really in my department. And any kind of crime does not come to the Public Prosecutor until the case against an accused person is ready to be presented.”

“It is a pity,” said Lord Farmley. “I could wish that the matter of the Frogs was not entirely in the hands of Scotland Yard. It is so out of the ordinary, and such a menace to society, that I should feel more happy if some extra department were controlling the investigations.”

Dick Gordon might have said that he was itching to assume that control, but he refrained. His lordship fingered his shaven chin thoughtfully. He was an austere man of sixty, delicately featured, as delicately wrinkled, the product of that subtle school of diplomacy which is at once urbane and ruthless, which slays with a bow, and is never quite so dangerous as when it is most polite.

“I will speak to the Prime Minister,” he said. “Will you dine with me, Captain Gordon?”

Early in the next afternoon, Dick Gordon was summoned to Downing Street, and was informed that a special department had been created to deal exclusively with this social menace.

“You have carte blanche, Captain Gordon. I may be criticized for giving you this appointment, but I am perfectly satisfied that I have the right man,” said the Prime Minister; “and you may employ any officer from Scotland Yard you wish.”

“I’ll take Sergeant Elk,” said Dick promptly, and the Prime Minister looked dubious.

“That is not a very high rank,” he demurred.

“He is a man with thirty years’ service,” said Dick; “and I believe that only his failure in the educational test has stopped his further promotion. Let me have him, sir, and give him the temporary rank of Inspector.”

The older man laughed.
