"Any time you happen to be passing," said young Mr. Nape rising to go, "call in and see my little laboratory; I’ve fixed it up in the greenhouse; if you ever want a blood stain analysed I shall be there." "Sitting in your dressing gown, I suppose," said the Duke with awe, "playing your violin and smoking shag?" Young Mr. Nape frowned. "Somebody has been talking about me," he said severely. III "63 has to call, 51 is out of town, and 35 has measles in the house," reported the Duke one morning at breakfast. Hank helped himself to a fried egg with the flat of his knife. "What about next door!" he asked. "Next door won’t call," said the Duke sadly. "Next door used to live in Portland Place, where dukes are so thick that you have to fix wire netting to prevent them coming in at the window—no, mark off 66 as a non-starter." Hank ate his egg in silence. "She’s very pretty," he said at length. "66?" Hank nodded. "I saw her yesterday, straight and slim, with a complexion like snow——" "Cut it out!" said the Duke brutally. "And eyes as blue as a winter sky in Texas." "Haw!" murmured his disgusted grace. "And a walk——" apostrophized the other dreamily. The Duke raised his hands. "I surrender, colonel," he pleaded; "you’ve been patronizing the free library. I recognize the bit about the sky over little old Texas." "What happened——?" Hank jerked his head in the direction of No. 66. The Duke was serious when he replied. "Africans, Siberians, Old Nevada Silver and all the rotten stock that a decent, easy-going white man could be lured into buying," he said quietly; "that was the father. When the smash came he obligingly died." Hank pursed his lips thoughtfully. "It’s fairly tragic," he said, "poor girl." The Duke was deep in thought again. "I must meet her," he said briskly. Hank looked at the ceiling. "In a way," he said slowly, "fate has brought you together, and before the day is over, I’ve no doubt you will have much to discuss in common." The Duke looked at him with suspicion. "Have you been taking a few private lessons from young Sherlock Nape?" he asked. Hank shook his head. "There was a certain tabby cat that patronized our back garden," he said mysteriously. "True, O seer!" "She ate our flowers." "She did," said the Duke complacently. "I caught her at it this very morning." "And plugged her with an air-gun?" "_Your_ air-gun," expostulated the Duke hastily. "Your plug," said Hank calmly, "well, that cat——" "Don’t tell me," said the Duke, rising in his agitation—"don’t tell me that this poor unoffending feline, which your gun——" "Your shot," murmured Hank. "Which your wretched air-gun so ruthlessly destroyed," continued the Duke sternly, "don’t tell me it is the faithful dumb friend of 66?" "It _was_," corrected Hank. "The devil it was!" said his grace, subsiding into gloom. IV
