“I will make all clear. The Prime Minister was in his car, his secretary beside him. Suddenly a pad of chloroform is clapped on his face——”

“But by whom?”

“By the clever linguistic Captain Daniels. As soon as the Prime Minister is unconscious, Daniels picks up the speaking-tube, and directs O’Murphy to turn to the right, which the chauffeur, quite unsuspicious, does. A few yards down that unfrequented road, a large car is standing, apparently broken down. Its driver signals to O’Murphy to stop. O’Murphy slows up. The stranger approaches. Daniels leans out of the window, and, probably with the aid of an instantaneous anæsthetic, such as ethylchloride, the chloroform trick is repeated. In a few seconds, the two helpless men are dragged out and transferred to the other car, and a pair of substitutes take their places.”

“Impossible!”

Pas du tout! Have you not seen music-hall turns imitating celebrities with marvellous accuracy? Nothing is easier than to personate a public character. The Prime Minister of England is far easier to understudy than Mr. John Smith of Clapham, say. As for O’Murphy’s ‘double,’ no one was going to take much notice of him until after the departure of the Prime Minister, and by then he would have made himself scarce. He drives straight from Charing Cross to the meeting-place of his friends. He goes in as O’Murphy, he emerges as some one quite different. O’Murphy has disappeared, leaving a conveniently suspicious trail behind him.”

“But the man who personated the Prime Minister was seen by every one!”

“He was not seen by anyone who knew him privately or intimately. And Daniels shielded him from contact with anyone as much as possible. Moreover, his face was bandaged up, and anything unusual in his manner would be put down to the fact that he was suffering from shock as a result of the attempt upon his life. Mr. MacAdam has a weak throat, and always spares his voice as much as possible before any great speech. The deception was perfectly easy to keep up as far as France. There it would be impracticable and impossible—so the Prime Minister disappears. The police of this country hurry across the Channel, and no one bothers to go into the details of the first attack. To sustain the illusion that the abduction has taken place in France, Daniels is gagged and chloroformed in a convincing manner.”

“And the man who has enacted the part of the Prime Minister?”

“Rids himself of his disguise. He and the bogus chauffeur may be arrested as suspicious characters, but no one will dream of suspecting their real part in the drama, and they will eventually be released for lack of evidence.”

“And the real Prime Minister?”
