The distant rumble of thunder had been coming closer to us. The rain had almost stopped, but, as Sir George opened the door, over the ominous stillness flashed a terrific fork of lightning, followed instantly by a crash near at hand. A blue-white streak ran down the bole of a tree across the road. The thunder that followed echoed and re-echoed above our heads as we faced each other in the firelight. Sir George had closed the door precipitately, but, as the noise died away, he jammed his cap over his ears and resolutely prepared for flight. Argument had no effect on him. Whatever had caused his sudden change of mind, he was determined to leave at once. I was panic-stricken. He had been my patent of respectability so far in what was, to say the least, an unconventional situation. But to have him go like that and leave me there with an ordinary thief, even if he did look like a Greek god except his nose, which was modern--(I do not like those old Greek noses, anyhow; they begin so far up on the forehead)--to have him leave me like that was dreadful. However, there came an interruption just then, a splashing of horses' feet along the road and the sound of men's voices. They halted just outside the gates and we caught a word here and there: "Gresham Place," and "Automobile," and one sentence that stuck in my mind and brought me a picture of myself in a hideous prison cap, sewing bags. It was: "Half a dozen are watching Ivry Manor House!" I think Sir George realised when I did that it was a searching party for him; he had been leaning against the door, listening. Suddenly he bolted for the keg where he had left his mackintosh, and picked it up. But The Unknown was before him. He quickly locked the outer door and stood with his back against it. "I cannot allow you to go out, sir," he said very politely. "Whether those men are searching for you or are hunting for--for some one else, you and I have a duty to perform: we must protect this young lady. In fact, and however strongly you may feel against it, I hope, sir, you will see the wisdom of shielding all the women concerned from publicity. And in this case it is not chivalry; it is self-protection." Sir George wavered. "You can see what the papers will make of it, sir. That the plot has failed would not check the general excitement; the situation is ludicrous instead of serious. That is the difference." Sir George sat down heavily and groaned. Perhaps I imagined it, but he looked older, leaner, paler than he had done earlier in the evening. "I have this plan to offer," pursued The Unknown. "We will get the machine from Bagsby in an hour"--he consulted a handsome watch; I wondered whose it had been--"and I will take you wherever you wish; to Gresham Place, or, if you will feel safer back in town, to the express for London. You can get it at East Newbury. If--if the young lady wishes, we will drop her at Ivry on the way."
