"Friends of your patient," Wilfrid said glibly. "They have come from London on urgent business. I presume they were not aware that Mr. Flower was so ill. They will stay till morning on the chance of Mr. Flower's being able to see them."

The nurse smiled grimly.

"There is no reason why they shouldn't wait, sir," he said. "But it is precious little business Mr. Flower will be able to transact for some time to come. I hope he was all right while I was away."

Wilfrid smiled in non-committal fashion. On the whole, it seemed best to say nothing about the patient's escapade.

"You had better get yourself some tea or coffee," he said. "I don't mind sitting up for another hour or so, and then I shall go to bed."

The nurse made his preparations by means of a spirit-lamp which he had in the dressing-room. Meanwhile, Wilfrid sat in a chair before the fire and dozed off. He was utterly fagged. The anxieties of the day had told upon him more than he was aware. At last the nurse aroused him and intimated that one of the gentlemen downstairs wished to speak to him. In the interval Uzali and Russell had not wasted their time. At first they sat smoking and helping themselves freely to the decanters on the table till Uzali grew more taciturn and appeared to be listening intently.

"What is the matter?" Russell asked.

"Our friends are beginning to move," Uzali said in a whisper. "I have not been far out in my deductions and, if you will oblige me, I shall be glad if you will throw your cigarette into the fire whilst I turn the light off."

Russell obeyed without comment. He felt he was entirely in the hands of his companion. Uzali proceeded to shut off the light and also to open one of the windows that led to the lawn. He placed a screen across the fire and nodded with the air of a man who is satisfied with his plans.

"All right so far," he muttered. "Now I want you to stand by the window with me, keeping quiet and being on the alert for what is going to take place. You will not find it so very dark when your eyes become accustomed to the gloom."
