The lieutenant, with his back turned to us, exploded with an indescribable laugh and swung round to face us. It was a laugh, the purport of which was direct and essential, and yet which one cannot exactly express. As near as it said anything, verbally speaking, it said: “Well, if you must spoil it, you must. But you don't know what you're spoiling.” “There is another thing,” continued Mr Montmorency weakly. “Of course, if you don't want to be visited you'll paint the house green, but--” “Green!” shouted Keith. “Green! Let it be green or nothing. I won't have a house of another colour. Green!” and before we could realize anything the door had banged between us and the street. Rupert Grant seemed to take a little time to collect himself; but he spoke before the echoes of the door died away. “Your client, Lieutenant Keith, appears somewhat excited,” he said. “What is the matter with him? Is he unwell?” “Oh, I should think not,” said Mr Montmorency, in some confusion. “The negotiations have been somewhat difficult--the house is rather--” “Green,” said Rupert calmly. “That appears to be a very important point. It must be rather green. May I ask you, Mr Montmorency, before I rejoin my companion outside, whether, in your business, it is usual to ask for houses by their colour? Do clients write to a house-agent asking for a pink house or a blue house? Or, to take another instance, for a green house?” “Only,” said Montmorency, trembling, “only to be inconspicuous.” Rupert had his ruthless smile. “Can you tell me any place on earth in which a green house would be inconspicuous?” The house-agent was fidgeting nervously in his pocket. Slowly drawing out a couple of lizards and leaving them to run on the counter, he said: “No; I can't.” “You can't suggest an explanation?” “No,” said Mr Montmorency, rising slowly and yet in such a way as to suggest a sudden situation, “I can't. And may I, as a busy man, be excused if I ask you, gentlemen, if you have any demand to make of me in connection with my business. What kind of house would you desire me to get for you, sir?” He opened his blank blue eyes on Rupert, who seemed for the second staggered. Then he recovered himself with perfect common sense and answered: “I am sorry, Mr Montmorency. The fascination of your remarks has unduly delayed us from joining our friend outside. Pray excuse my apparent impertinence.” “Not at all, sir,” said the house-agent, taking a South American spider idly from his waistcoat pocket and letting it climb up the slope of his desk. “Not at all, sir. I hope you will favour me again.” Rupert Grant dashed out of the office in a gust of anger, anxious to face Lieutenant Keith. He was gone. The dull, starlit street was deserted. “What do you say now?” cried Rupert to his brother. His brother said nothing now.
