The Island of Sheep by John Buchan

Sandy departed next morning, and, as usual, was not communicative about his plans. I wanted him to see Haraldsen, but he said that there was no need, and that the sooner he was in London the better. He asked for Lombard's address and a line of introduction to him, and his only instruction was to keep Haraldsen safe for the next week. He suggested that to look after him might be made a whole- time job for Peter John.

Peter John took on the task joyfully, for here was something after his own heart. He worshipped Sandy, and to be employed by him thrilled him to the marrow. Besides, he had struck up with Haraldsen one of those friendships that a shy, self-contained boy very often makes with a shy man. Haraldsen came twice to dinner during the week after Sandy left, and there was no mistake about the change for the better in his condition. He spoke of his daughter at school without the flicker of fear in his eyes which had distressed me. He was full of questions about our small woodland birds, which were mostly new to him, and to which Peter John was introducing him. He was even willing to talk about his Island of Sheep without a face of blank desolation.
