He laid his hand lightly on Sir Arthur's shoulder. He woke at once and drank his coffee. Then he asked how Vane was, and when he knew that he was sleeping again, and would not wake for some hours, he got up, undressed, and had a bath and dressed again.

Then, after a not very successful attempt at breakfast, he went out and turned into the Hammersmith Road in the direction of Brook Green. He remembered the address that Miss Carol had given Vane just as he remembered every other word of the conversation. He had determined to call upon her, and to make as sure as possible that his dreadful suspicions were correct before he told Vane the truth.

He found No. 15, Melville Gardens, one of a row of neat little detached houses; not much more than cottages, but cosy and comfortable-looking, each with a tiny little plot of ground in front and behind, and with a row of trees down each side of the road which seemed to stand in apologetic justification of the title of gardens.

The door was opened by a neatly-dressed, motherly-looking woman of about forty instead of by the dishevelled, smutty-faced maid-of-all-work that he half expected to find.

"Does Miss Carol Vane live here?" he asked, with a curious feeling of nervousness.

"Yes, sir, she and Miss Murray are just finishing breakfast. Will you come in and sit down, sir? Miss Vane won't be long."

"Thank you, yes," he said, going in. "I wish to see her rather particularly."

"What name shall I say, sir?" said the woman, as she showed him into a prettily-furnished little sitting-room opening out into the back garden with French windows.

"Sir Arthur Maxwell," he replied. "If you will give my compliments to Miss Vane, and tell her that she will do me a great service by giving me about half-an-hour's conversation, I shall be much obliged to you."

The housekeeper made something like a little curtsey as she left the room. She was distinctly impressed by the stately presence and old-world courtesy of this bronzed, white-haired gentleman. He was so very different from the general run of visitors at No. 15; but she had half guessed his errand before she knocked at the door of the front room in which Miss Carol and her friend and house-mate, Dora Murray, were finishing their last cup of tea.
