"Well, my lord, allow me to confide in you. Medical men mostly keep their knowledge in such matters to themselves. We know and recognise symptoms which to you are invisible. By these symptoms—by those symptoms," he repeated slowly and looking hard at the other man, "I know that this man—no longer Oxbye, my patient, but—another—is in a highly dangerous condition. I have noted the symptoms in my book"—he tapped his pocket—"for future use."
"And when—when——" Lord Harry was frightfully pale. His lips moved, but he could not finish the sentence. The Thing he had agreed to was terribly near, and it looked uglier than he had expected.
"Oh! when?" the doctor replied carelessly. "Perhaps to-day—perhaps in a week. Here, you see, Science is sometimes baffled. I cannot say."
Lord Harry breathed deeply. "If the man is in so serious a condition," he said, "is it safe or prudent for us to be alone in the house without a servant and without a nurse?"
"I was not born yesterday, my lord, I assure you," said the doctor in his jocular way. "They have found me a nurse. She will come to-day. My patient's life is, humanly speaking"—Lord Harry shuddered—"perfectly safe until her arrival."
"Well—but she is a stranger. She must know whom she is nursing."
"Certainly. She will be told—I have already told her—that she is going to nurse Lord Harry Norland, a young Irish gentleman. She is a stranger. That is the most valuable quality she possesses. She is a complete stranger. As for you, what are you? Anything you please. An English gentleman staying with me under the melancholy circumstances of his lordship's illness. What more natural? The English doctor is staying with his patient, and the English friend is staying with the doctor. When the insurance officer makes inquiries, as he is very likely to do, the nurse will be invaluable for the evidence she will give."
He rose, pulled up the blinds noiselessly, and opened the windows. Neither the fresh air nor the light awoke the sleeping man.
Vimpany looked at his watch. "Time for the medicine," he said. "Wake him up while I get it ready."
"Would you not—at least—-suffer him to have his sleep out?" asked Lord Harry, again turning pale.
