“Not at present.”

Captain Griffiths glanced between his horse's ears for a few moments. Then he turned once more towards his companion.

“Mr. Lessingham,” he said, “you are aware that I am Commandant here?”

“I believe,” Lessingham replied, “that Lady Cranston told me so.”

“It is my duty, therefore,” Griffiths went on, “to take a little more than ordinary interest in casual visitors, especially at this time of the year. The fact that you are well-known to Lady Cranston is, of course, an entirely satisfactory explanation of your presence here. At the same time, there is certain information concerning strangers of which we keep a record, and in your case there is a line or two which we have not been able to fill up.”

“If I can be of any service,” Lessingham murmured.

“Precisely,” the other interrupted. “I knew you would feel like that. Now your arrival here—we have the date, I think—October 6th. As you have just remarked, you didn't come by train. How did you come?”

Lessingham's surprise was apparently quite genuine.

“Is that a question which you ask me to answer—officially?” he enquired.

His interlocutor shrugged his shoulders.
