"This," he made answer. "Something which looks as if there were at least two women in this room last night, and Lady Margaret herself was one of them." He held up the object as he spoke. It was a long, glittering gold scarf from the end of which a fragment had been torn violently away. Taking out his pocketbook, Cleek unfolded with trembling fingers the torn scrap of lace found clutched in the dead hand and fitted it into the damaged place.

"By James!" Mr. Narkom gasped, letting the scarf drop like a golden snake to the ground. "It fits; it fits. Cleek! how could that child have perpetrated a deed like that and escape, vanish without a sound? It is impossible—utterly and ridiculously impossible!"

Cleek made no reply. His mind sped back over his last chat with Ailsa. What was it that she had said? The scarf had been given Lady Margaret by her dead father. H'mn—a valued possession, then, not likely to be given up lightly, or even lent, much less left about like this.

"Perhaps someone stole it," suggested Mr. Narkom.

"But who; and why leave it here?" responded Cleek, grimly. "It must be the identical scarf, the fragment proves that, and yet—Lady Brenton has one, Miss Jennifer has another——" his words trailed away again as the complexities of the clue were borne in on him.

Certainly there had been two women abroad in the neighbourhood of the house on the night of the murder. Two, possibly three. But even if one were Lady Margaret herself this could not absolutely convict her of murder. It would take more than a young girl's strength to overpower an active man, and yet—despair lends strength.

Before, however, either of them could voice the thoughts that were racing through their minds, the sound of excited voices, and heavy trampling feet coming up the drive toward the house for the moment drove all other thoughts out of their minds.

"Come along down, Cleek," said Mr. Narkom, his voice shaking with excitement. "It's Hammond and Petrie. I set them to search the grounds and the river. It seems as if they had discovered something startling from the noise."
