THE INNOCENCE OF FATHER BROWN
its owner; he needed no stoves or lamps, he would say, but carried his own warmth with him. But when Merton recalled the other inmates, he was compelled to confess that they also were as shadows of their lord. The moody man-servant, with his monstrous black gloves, was almost a nightmare; Royce, the secretary, was solid enough, a big bull of a man, in tweeds, with a short beard; but the straw-coloured beard was startlingly salted with grey like the tweeds, and the broad forehead was barred with premature wrinkles. He was good-natured enough also, but it was a sad sort of good-nature, almost a heart-broken sort—he had the general air of being some sort of failure in life. As for Armstrong's daughter, it was almost incredible that she was his daughter; she was so pallid in colour and sensitive in outline. She was graceful, but there was a quiver in the very shape of her that was like the lines of an aspen. Merton had sometimes wondered if she had learnt to quail at the crash of the passing trains.
"You see," said Father Brown, blinking modestly, "I'm not sure that the Armstrong cheerfulness is so very cheerful—for other people. You say that nobody could kill such a happy old man, but I'm not sure; ne nos inducas in tentationem. If ever I murdered somebody," he added quite simply, "I dare say it might be an Optimist."
"Why?" cried Merton amused. "Do you think people dislike cheerfulness?"
