"The enemy have arrived," murmured Jack, and his father nodded. They stole swiftly across the room and peered through the little apertures which lighted the place. No better spying-place could be needed. They looked straight into the broad open space before the pagoda, and saw their pursuers defiling from a narrow street. One man was mounted, and they knew him at once for U Saw, the great ruby in his head-dress glinting scarlet fire in the rays of the sun. At the tail of his horse strode the Strangler, and a dozen busy little blue-kilted figures ran hither and thither, chattering and calling to each other, and searching eagerly for traces of the fugitives.

A loud shout presently told the Haydons that something had been discovered. Half a dozen Kachins began to yell together, and Mr. Haydon listened intently.

"They've found the hole," he murmured coolly. "What next?"

"It's very lucky for us that Mrs. Stripes is at home and on guard," said Jack. "We could hold them in the narrow stairs there with our dahs, but she'll do the job much better."

"Yes, for a time, without doubt," replied his father, shaking his head. "But these chaps are splendid little shikarees, and fear nothing that stands on four legs."

They could not see the group of Kachins which had gathered before the opening, but they saw the Ruby King wave his hand, and knew that the blue-kilts had been ordered to explore. They listened breathlessly, but, for some moments, all was silence. Then in the vault below there broke out a frightful roar of anger, and mingled with it came yells and outcries. The two watchers looked eagerly from their apertures, and saw the Kachins recoiling in a disorderly body, carrying among them a man whose legs dragged along the ground.

"Looks as if she'd settled one of them," remarked Mr. Haydon. It was soon apparent that the tigress had thinned by one the number of their enemies. The man was laid down in the open space, and his fellows gathered about him. But very soon they left the body lying where it had been placed, and collected about the Ruby King in a chattering crowd.

"Clearly the man is dead," said Jack. "They do not attempt to do anything for him."

"I should say she smashed his skull in, by the look of things from this distance," remarked his father. "See how the blood spreads in a pool about his head!"

Their eyes were fixed on the debating crowd, and they were wondering what the next move of the Kachins would be, when they heard a low call behind them. Both whirled round at once, and saw that it was their companion who was attracting their attention. She was kneeling on the floor, and they ran to her at once. She knelt beside a large stone which was sunk three or four inches below its fellows and shook easily under the touch.
