"Was there any reason for this?" inquired the detective, looking keenly at Cyril.
"I was never very friendly with my cousin, and we sailed for South Africa immediately after our marriage. Neither of us has been home since then."
"I must find out where she spent the night of the murder," murmured the Inspector. He seemed to have forgotten Cyril's presence.
"If you think her Ladyship had anything to do with the tragedy, I assure you, you are on the wrong track," cried Cyril, forgetting for a moment his pose of polite aloofness. "She has never been at all violent. It is chiefly her memory that is affected. Until the last few days what she did one minute, she forgot the next."
"You think, therefore, that she would not be able to tell me how she spent her time in Newhaven?"
"I am sure of it."
"That is most unfortunate! By the way, how has she taken the news of Lord Wilmersley's murder?"
"She has not been told of it. She does not even know that he is dead."
"Ah!"
"I see I must explain her case more fully, so that you may be able to understand my position. Her Ladyship's mind became affected about six months ago, owing to causes into which I need not enter now. Since her arrival in England her improvement has been very rapid. Her memory is growing stronger, but it is essential that it should not be taxed for the present. The doctor assures me that if she is kept perfectly quiet for a month or so, she will recover completely. That is why I want her to remain in absolute seclusion. An incautious word might send her off her balance. She must be protected from people, and I will protect her, I warn you of that. Six weeks from now, if all goes well, you can cross-question her, if you still think it necessary, but at present I not only forbid it, but I will do all in my power to prevent it. Of course," continued Cyril more calmly, "I have neither the power nor the desire to hamper you in the exercise of your profession; so if you doubt my statements just ask Dr. Stuart-Smith whether he thinks her Ladyship has ever been in a condition when she might have committed murder. He will laugh at you, I am sure."
