Then I remembered the inspector's statement. Had there been a possible way to get in that house that night, surely he would have found it. That would not require very clever detective work.

Suddenly a thought struck me, which turned my heart to ice. It was I who had first testified that the chain was on the door when Charlotte opened it that morning! If I had not mentioned it, perhaps no one would have thought of it, and it would have been assumed that the criminal forced his way in at the front door.

That would have left a loophole for doubt. Now they said there was none. Oh, how could I have been so stupid as to tell of that chain? I who desired only to serve and assist the woman I loved—I had done the one thing, said the one word, that gave those men reason to say she had "exclusive opportunity"!

That, then, was why Doctor Masterson had looked so perturbed at my testimony. That was why he was worried and nervous at Charlotte's mention of the chain. That was why he looked relieved when Laura completed her account without referring to that awful bit of evidence.

And why didn't Laura refer to it? Perhaps she thought it would be a point which couldn't be explained, which was as inexplicable to her as to me, but which no more proved Miss Pembroke guilty than it proved the angels in heaven to be criminals.

Janet had regained consciousness, but still lay on the couch, with closed eyes, and the inexorable coroner called George Lawrence.

The young man seemed to be controlling himself by a mighty effort.

"I see your implication," he said to the coroner, "and I want you to retract it. My cousin, Miss Pembroke, is incapable of such a thing as you hint, and the mere fact of a chained front door does not preclude other modes of housebreaking. I am by no means sure the windows were all securely fastened last night. Indeed, I am forced to believe they were not, since somebody came in and killed my uncle, and it was not my cousin Janet."

"There has been no accusation," said the coroner coldly. "Will you now give us your testimony?"

"I can tell you nothing to throw any light on the mystery," said George Lawrence, who was, apparently, holding himself well in hand. "I called here yesterday afternoon between five and six. My uncle was very cross and grumpy, and gave me no pleasant word while I was here. He was not at that time definitely angry, but merely testy and irritable. I talked for a time with Janet, and went away about six.
