“Gone!” said Sir Patrick. “This looks bad.”

After a moment’s reflection he went back into the hall to get his hat. It was possible that she might have been afraid of discovery if she staid in the library, and that she might have gone on to the summer-house by herself.

If she was not to be found in the summer-house, the quieting of Blanche’s mind and the clearing up of her uncle’s suspicions alike depended on discovering the place in which Miss Silvester had taken refuge. In this case time would be of importance, and the capacity of making the most of it would be a precious capacity at starting. Arriving rapidly at these conclusions, Sir Patrick rang the bell in the hall which communicated with the servants’ offices, and summoned his own valet—a person of tried discretion and fidelity, nearly as old as himself.

“Get your hat, Duncan,” he said, when the valet appeared, “and come out with me.”

Master and servant set forth together silently on their way through the grounds. Arrived within sight of the summer-house, Sir Patrick ordered Duncan to wait, and went on by himself.

There was not the least need for the precaution that he had taken. The summer-house was as empty as the library. He stepped out again and looked about him. Not a living creature was visible. Sir Patrick summoned his servant to join him.

“Go back to the stables, Duncan,” he said, “and say that Miss Lundie lends me her pony-carriage to-day. Let it be got ready at once and kept in the stable-yard. I want to attract as little notice as possible. You are to go with me, and nobody else. Provide yourself with a railway time-table. Have you got any money?”

“Yes, Sir Patrick.”

“Did you happen to see the governess (Miss Silvester) on the day when we came here—the day of the lawn-party?”

“I did, Sir Patrick.”
