"It may have been man or woman," replied the Chinaman, "but the feet were cut and were bleeding. There is mark of blood on the gravel outside."
"Nonsense!" said Whiteside sharply.
"Let him go on," warned Tarling.
"A woman came in and went out——" continued Ling Chu.
"That was Miss Rider," said Tarling.
"Then a woman and a man came; then the bare-footed one came, because the blood is over the first women's footmarks."
"How do you know which was the first woman and which was the second?" asked Whiteside, interested in spite of himself.
"The first woman's foot was wet," said Ling Chu.
"But there had been no rain," said the detective in triumph.
"She was standing on the grass," said Ling Chu, and Tarling nodded his head, remembering that the girl had stood on the grass in the shadow of the bushes, watching his adventure with Milburgh.
