“Ah, here is Lady Stanworth,” the inspector observed, with a slight bow.

Lady Stanworth inclined her head coldly. “You wish me to be present at this formality, Inspector?” she asked distantly.

The inspector looked slightly taken aback.

“Well, I think it would be better, my lady,” he replied, a trifle deprecatingly. “As the only surviving relative of the deceased’s, you know. But of course if you have any——”

“I was not a relative of Mr. Stanworth’s,” Lady Stanworth interrupted in the same tone. “I thought I had made that clear to you this morning. He was my brother-in-law.”

“Quite so, quite so,” said the inspector apologetically. “I should perhaps have said connection. It is usual for the nearest connection to be present when——”

“I ought to have warned you, perhaps, Lady Stanworth,” Jefferson put in evenly. “But, unfortunately, I have not seen you to do so since before lunch; and I did not care to take the responsibility of disturbing you. The opening of the safe is, after all, a mere formality; and both the inspector and myself have no doubt that nothing of any importance will be found. Nothing whatever.”

Lady Stanworth looked hard at the last speaker for a moment, and when she spoke again the former coldness of her tone had completely disappeared.

“Of course I will come if you think it better, Inspector,” she said graciously. “There is really no reason whatever why I should not do so.” And without more ado she led the way towards the library.

Roger brought up the rear of the little party. He was thinking furiously. He had watched the little exchange that had just taken place with feelings almost of bewilderment. It was so unlike Lady Stanworth to go out of her way to snub the poor inspector in that highly unnecessary manner. Why had she done so? And why had she been so very much on the high horse with regard to the opening of the safe? It seemed almost as if she had been really apprehensive of something, and had adopted this attitude in order to cloak her actual feelings. But if that were the case, what earthly reason could she have for apprehension? Roger asked himself despairingly.
