Mme. Estelle started and looked at him, half in terror, half in admiration.

“It is a bold plan,” she said.

“A bold plan,” Melun agreed, “and a plan which must succeed if you will help me. The difficulty is to get the girl away, and I shall have to leave that entirely to you. What is more, there is very little time to be lost. The Cabinet meets at noon, and for a couple of hours after that Lord Penshurst will be busy with his colleagues. Consequently during that time Lady Kathleen will be alone.

“Fortunately I managed to put young Hilden out of the way, at least for a time, so that we shall be free of his prying and peeping and officiousness when you call to-day.”

“When I call to-day!” repeated Madame in tones of wonderment.

“Yes, yes,” continued Melun; “it is you who will have to call. As things are at present it is naturally impossible for me to show my face near Downing Street. With you, however, the matter is quite different. No one there knows you.

“Now I have left nothing to chance. Westerham, if you please, must go nosing around the garage in Rupert Street to find out where his car is. It had gone, of course, to Holyhead as the result of my instructions. The manager wired to the chauffeur at Chester to return to town at once. But I wired to Birmingham to stop it there. Crow went down and dismissed the chauffeur, saying that he came from Westerham. The car is now in Chelsea, and we shall have the pleasure of using it to-day. It is just the car we want, because for some reason or other Westerham had it fitted with blind shutters.”

Madame nodded her head.

“We will telephone to Westminster and get the car to meet us at Oxford Circus. You can go down to Downing Street, and I will take a taxicab to the Star and Garter, Richmond. When you get to No. 10 simply ask for the Lady Kathleen, but give no name and refuse your business. That will merely arouse her curiosity, and the fact that you come in such a car will certainly obtain you an audience.”

Melun then went on to give Madame various instructions, enjoining her not to talk to Lady Kathleen on the way down to Richmond.
