"I could get very little from the travelling inspector, except that his daughter was under the impression that the lady had a grudge against Mr. Lyne, and that she spoke even more disparagingly of Mr. Milburgh."

Tarling had risen and slipped off his silk dressing-gown before the other could put away his notebook. He struck a gong with his knuckles, and when Ling Chu appeared, gave him an order in Chinese, which Whiteside could not follow.

"You're going to Ashford? I thought you would," said Whiteside. "Would you like me to come along?"

"No, thank you," said the other. "I'll go myself. I have an idea that Miss Stevens may be the missing witness in the case and may throw greater light upon the happenings of the night before last than any other witness we have yet interviewed."

He found he had to wait an hour before he could get a train for Ashford, and he passed that hour impatiently walking up and down the broad platform. Here was a new complication in the case. Who was Miss Stevens, and why should she be journeying to Dover on the night of the murder?

He reached Ashford, and with difficulty found a cab, for it was raining heavily, and he had come provided with neither mackintosh nor umbrella.

The matron of the Cottage Hospital reassured him on one point.

"Oh, yes, Miss Stevens is still in the hospital," she said, and he breathed a sigh of relief. There was just a chance that she might have been discharged, and again the possibility that she would be difficult to trace.

The matron showed him the way through a long corridor, terminating in a big ward. Before reaching the door of the ward there was a smaller door on the right.

"We put her in this private ward, because we thought it might be necessary to operate," said the matron and opened the door.
