Sir Julian came back with a start to the consideration of actuality.

“Your work calls you?” he said, smiling. “Well, I can understand that. I won’t keep you. But I wanted to say something to you in connection with your present inquiry—only I hardly know—I hardly like—”

Parker sat down again, and banished every indication of hurry from his face and attitude.

“I shall be very grateful for any help you can give me,” he said.

“I’m afraid it’s more in the nature of hindrance,” said Sir Julian, with a short laugh. “It’s a case of destroying a clue for you, and a breach of professional confidence on my side. But since—accidentally—a certain amount has come out, perhaps the whole had better do so.”

Mr. Parker made the encouraging noise which, among laymen, supplies the place of the priest’s insinuating, “Yes, my son?”

“Sir Reuben Levy’s visit on Monday night was to me,” said Sir Julian.

“Yes?” said Mr. Parker, without expression.

“He found cause for certain grave suspicions concerning his health,” said Sir Julian, slowly, as though weighing how much he could in honour disclose to a stranger. “He came to me, in preference to his own medical man, as he was particularly anxious that the matter should be kept from his wife. As I told you, he knew me fairly well, and Lady Levy had consulted me about a nervous disorder in the summer.”

“Did he make an appointment with you?” asked Parker.
