"Certainly it is," Miss Gates replied. "We are all agreed about that."

"Because I read the number over the fanlight," Steel went on. "And I came here by arrangement. And there was everything as I see it now. Bell, you must either cure me of this delusion, or you must prove logically to me that I have made a mistake. So far as I am concerned, I am like a child struggling with the alphabet."

"We'll start now," said Bell. "Come along."

Steel rose none too willingly. He would fain have lingered with Ruth. She held out her hand; there was a warm, glad smile on her face.

"May you be successful," she whispered. "Come and see me again, because I shall be very, very anxious to know. And I am not without guilt…. If you only knew!"

"And I may come again?" David said, eagerly.

A further smile and a warm pressure of the hand were the only reply. Presently Steel was standing outside in the road with Bell. The latter was glancing at the house on either side of 219. The higher house was let; the one nearest the sea—218—was empty. A bill in the window gave the information that the property was in the hands of Messrs. Wallace and Brown, Station Quadrant, where keys could be obtained.

"We'll make a start straightaway," said Bell. "Come along."

"Where are you going to at that pace?" Steel asked.

"Going to interview Messrs. Wallace and Brown. At the present moment I am a gentleman who is in search of a house of residence, and I have a weakness for Brunswick Square in particular, especially for No. 218. Unless I am greatly mistaken I am going to show you something that will startle even the most callous novelist."
