Ned's mouth shut hard and his eyes turned to the fire. He said nothing for a moment and then remarked:
"Well, I guess that's worth thinking over."
Carrington's shoulders moved in an almost imperceptible shrug, but he made no comment aloud. In a moment Ned said:
"Supposing those two are scored out, there doesn't seem to be anybody else inside the house who could have committed the crime, does there? You wouldn't suspect Lady Cromarty or Bisset, would you?"
"Lady Cromarty is physically incapable of giving her husband the blow he must have received. Besides, they were a very devoted couple, I understand, and she gained nothing by his death—lost heavily, in fact. As for Bisset——" Carrington let his smile finish the sentence.
"Then it must have been some one from outside—but who?"
"Can you think of any one?" asked Carrington.
Ned shook his head emphatically.
"Can you?" he asked.
