"Garage close by, in Kingsway," answered Penteney, hurriedly seizing on one of several greatcoats that hung in a recess. "Here!—get into one of these—you're about my height, and the air's still nippy, motoring. Now come on—we'll be there in under the hour. You know," he continued, as they left the office and hastened towards Kingsway, "I think I see through something of this already, Hetherwick. These fellows probably believed they were kidnapping Lady Riversreade!—and got her sister in mistake for her. Ransom, you know! The blackmailing dodge failed—now they're trying this. A desperate and dare-devil lot, evidently!"

Hetherwick nodded a silent assent. He was wondering whether or not to tell Penteney that the Miss Featherstone of whom he had just spoken was in reality the granddaughter of the man whose mysterious murder appeared to be the starting-point of the more recent, equally mysterious events. That fact, it seemed to him, would have to come out sooner or later—and there might be possible complications, perhaps unpleasantness, when Lady Riversreade discovered that Rhona had gone to her as a spy. Might it not be well to take Penteney into his confidence and explain matters? But, on reflection, he decided to wait until they knew the exact situation at Riversreade Court; so far, in spite of Lady Riversreade's news he felt it difficult to believe that two women, one of them, to his knowledge, a girl of character and resource, and the other a woman of the world, used to travelling and to adventure, could be carried off in broad daylight in immediate prospect of two large houses—the thing seemed impossible.

CHAPTER XIX

THE LONDON ROAD

Some fifty minutes later, the big, powerful car, which Penteney had commissioned in Kingsway, dashed up to Riversreade Court. Hetherwick found that there had been no exaggeration in Lady Riversreade's telephone message. She herself came hurrying out to meet them; there were men standing about the terrace outside and others visible in the park; a couple of uniformed policemen followed Lady Riversreade from her study, where Hetherwick supposed her to have been in consultation with them. And her first glance was directed on Hetherwick himself; she addressed him before Penteney could go through any hurried introduction.

"I've seen you before!" she exclaimed abruptly. "You were with my secretary, Miss Featherstone, at Victoria, Sunday morning. Are you engaged to her?"

"No!" replied Hetherwick. "But we are close friends."

"Well, Miss Featherstone's been run away with—and so has my sister, Madame Listorelle," continued Lady Riversreade. "That's the long and short of it! You seemed almost incredulous when I rang you up," she continued, turning to Penteney, "but there's no doubt about it—they've been kidnapped, under my very windows. And we haven't a single clue, a trace of any sort."

"So far, you mean," answered Penteney coolly. "But come—but let me hear all about it. What are the details?"
