“What is Mr. Harley doing?”

“He tells me that he does not take breakfast, sir. Colonel Don Juan Menendez will be unable to ride with you this morning, but a groom will accompany you to the heath if you wish, which is the best place for a gallop. Breakfast on the south veranda is very pleasant, sir, if you are riding first.”

“Good,” I replied, for indeed I felt strangely heavy; “it shall be the heath, then, and breakfast on the veranda.”

Having drunk a cup of tea and dressed I went into Harley’s room, to find him propped up in bed reading the Daily Telegraph and smoking a cigarette.

“I am off for a ride,” I said. “Won’t you join me?”

He fixed his pillows more comfortably, and slowly shook his head.

“Not a bit of it, Knox,” he replied, “I find exercise to be fatal to concentration.”

“I know you have weird theories on the subject, but this is a beautiful morning.”

“I grant you the beautiful morning, Knox, but here you will find me when you return.”

I knew him too well to debate the point, and accordingly I left him to his newspaper and cigarette, and made my way downstairs. A housemaid was busy in the hall, and in the courtyard before the monastic porch a negro groom awaited me with two fine mounts. He touched his hat and grinned expansively as I appeared. A spirited young chestnut was saddled for my use, and the groom, who informed me that his name was Jim, rode a smaller, Spanish horse, a beautiful but rather wicked-looking creature.
