But how devilishly clever of Griggs to have deferred his attack until he was able to catch his adversary off his guard! Cyril looked keenly but, he hoped, calmly at the Inspector. Their eyes met, but without the clash which Cyril had expected. The man's expression, although searching, was not hostile; in fact, there was something almost apologetic about his whole attitude. Griggs was not sure of his ground, that much was obvious. He knew something, he probably suspected more, but there was still a chance that he might be led away from the trail. Cyril's mind worked with feverish rapidity. He realised that it was imperative that his manner should appear perfectly natural. But how would an innocent man behave? He must first decide what his position, viewed from Griggs's standpoint, really was. He must have a definite conception of his part before he attempted to act it. The Inspector evidently knew that a young woman, who bore Cyril's name, had been taken ill on the Newhaven train. He was no doubt also aware that she was now under the care of Dr. Stuart-Smith. But if the Inspector really believed the girl to be his wife, these facts were in no way incriminating. Yet the man smelt a rat! He must, therefore, know more of the truth. No, for if he had discovered that the girl was not Lady Wilmersley, Cyril was sure that Griggs would not have broached the subject so tentatively. What then had aroused the man's suspicions? Ah, he had it! He had told every one who inquired about his wife that she was still on the continent. Peter, also, obeying his orders, had repeated the same story in the servants' hall. And, of course, Griggs knew that they were both lying. No wonder he was suspicious! "She is much better, thank you. But how did you hear of her illness? I have not mentioned it to any one." Cyril flattered himself that his voice had exactly the right note of slightly displeased surprise. He watched the Inspector breathlessly. Had he said the right thing? Yes, for Griggs's expression relaxed and he answered with a smile that was almost deprecating: "I, of course, saw the report of the man who searched the train, and I was naturally surprised to find that the only lady who had taken her ticket in Newhaven was Mrs. Cyril Crichton. In a case like this we have to verify everything, so when I discovered that the gentleman who was with her, was undoubtedly your Lordship, it puzzled me a good deal why both you and your valet should be so anxious to keep her Ladyship's presence in England a secret." "Yes, yes, it must have astonished you, and I confess I am very sorry you found me out," said Cyril. He had his cue now. The old lie must be told once more. "Her Ladyship is suffering from a--a nervous affection." He hesitated purposely. "In fact--she has just left an insane asylum," he finally blurted out. "You mean that the present Lady Wilmersley--not the Dowager--?" The Inspector was too surprised to finish his sentence.
