Fairthorn had Lionel all to himself, and having within the last few days reindulged in open cordiality to the young guest, he was especially communicative that evening. He talked much on Darrell, and with all the affection that, in spite of his fear, the poor flute-player felt for his ungracious patron. He told many anecdotes of the stern man's tender kindness to all that came within its sphere. He told also anecdotes more striking of the kind man's sternness where some obstinate prejudice, some ruling passion, made him "granite." "Lord, my dear young sir," said Fairthorn, "be his most bitter open enemy, and fall down in the mire, the first hand to help you would be Guy Darrell's; but be his professed friend, and betray him to the worth of a straw, and never try to see his face again if you are wise,--the most forgiving and the least forgiving of human beings. But--" The study door noiselessly opened, and Darrell's voice called out, "Fairthorn, let me speak with you." CHAPTER XV. Every street has two sides, the shady side and the sunny. When two men shake hands and part, mark which of the two takes the sunny side: he will be the younger man of the two. The next morning, neither Darrell nor Fairthorn appeared at breakfast; but as soon as Lionel had concluded that meal, Mr. Mills informed him, with customary politeness, that Mr. Darrell wished to speak with him in the study. Study, across the threshold of which Lionel had never yet set footstep! He entered it now with a sentiment of mingled curiosity and awe. Nothing in it remarkable, save the portrait of the host's father over the mantelpiece. Books strewed tables, chairs, and floors in the disorder loved by habitual students. Near the window was a glass bowl containing gold-fish, and close by, in its cage, a singing-bird. Darrell might exist without companionship in the human species, but not without something which he protected and cherished,--a bird, even a fish. Darrell looked really ill: his keen eye was almost dim, and the lines in his face seemed deeper. But he spoke with his usual calm, passionless melody of voice. "Yes," he said, in answer to Lionel's really anxious inquiry; "I am ill. Idle persons like me give way to illness. When I was a busy man, I never did; and then illness gave way to me. My general plans are thus, if not actually altered, at least hurried to their consummation sooner than I expected. Before you came here, I told you to come soon, or you might not find me. I meant to go abroad this summer; I shall now start at once. I need the change of scene and air. You will return to London to-day." "To-day! You are not angry with me?"
