Heldon Foyle made a little gesture of dissent. "I don't think it likely. It would double the danger of identification. But we can soon find if she's gone back to her home. I told Taylor, who is watching in Berkeley Square, to report when she returned." He touched a bell and put a question to the man who entered. "Yes, sir," was the reply. "He rang up half an hour ago. You told me I wasn't to disturb you. He reported Lady Eileen Meredith had just gone in." "There you are, then, Green," said Foyle. "That point's settled. You get along. I wish I could come with you, but it won't do for me to leave London just now, and goodness knows where you may have to finish up. Good-bye and good luck." When Green had gone, Foyle gave a few instructions to cover the points that had arisen, and walked to Sir Hilary Thornton's room. The Assistant Commissioner looked up and proffered a cigar. "Think of the angels," he said. "I was just wondering how things were going." "Things are straightening out a bit," said the superintendent. "It's been a busy day, and it's not over yet." And, puffing a ring of smoke into the air, he told in bare, unadorned fashion the events of the day. "It has been a narrow thing for Grell," he concluded. "Even now, I fancy we shall get him. Green's as tenacious as a bull-dog when he's got something to take hold of." With his hands thrust deep in his trousers pockets, Sir Hilary strode to and fro across the room. "It's time we got a bit forward," he said. "The adjourned inquest will come on again soon, and we shan't be able to keep the question of identity up our sleeves any longer." "There's a week yet," answered Foyle. "I don't think it will much matter what is revealed then." The Assistant Commissioner came to a halt. "You're not a man to be over-confident, Foyle," he explained. "Do you feel pretty certain of having Grell under arrest by that time? I've not interfered with you hitherto, but for heaven's sake be careful. It won't do to make a mistake--especially with a man of Grell's standing." Heldon Foyle lifted his shoulders deprecatingly. "It all depends upon an idea I have, sir. I am willing to take all responsibility." "You're still convinced that Grell is guilty?" "I am convinced that he knows all about the murder," answered Foyle ambiguously. "With the help of Pinkerton's, I've traced his history back for the last twenty-five years. He's had his hands in some queer episodes in his time before he became a millionaire. There are gaps which we can't fill up, of course, but we're pretty complete. There was one thing in his favour. Although he's known toughs in all corners of the world, he's never been mixed up in any dirty business. And as he's carried out one or two political missions for the United States, I suppose he's had to know some of these people. To-morrow or the next day, I expect to have the records of both Ivan Abramovitch and Condit. It will all help, though the bearing on the murder is perhaps indirect."
