"Unfortunately not," regretted the Baron, and led the way indoors to a room which Mrs. Sherrill had hospitably insisted upon regarding as a private den of work and consultation for the Baron and his secretary. "There is a mission of exceeding delicacy," began Baron Tregar slowly, "which I feel I must inflict upon you." His deep, penetrating eyes lingered intently upon Philip's face. "It concerns the singular conveyance of green and white and the lady within it." Philip looked frankly astonished. "I take it then," he suggested, "that you know the nomadic lady, Baron Tregar?" "No," said the Baron. Philip stared. "Your Excellency is pleased to jest," he said politely. "On the contrary," said the Baron, "I am at a loss for suitable words in which to express my singular request. I am assured of your interest, Poynter?" "Of my interest, assuredly!" admitted Philip. "My compliance," he added fairly, "depends, of course, upon the nature of the mission." "It is absurdly simple," said the Houdanian suavely. "Merely to discover whether or not the nomadic lady feels any exceptional interest--in Houdania. For the information to be acquired in a careless, disinterested manner without arousing undue interest, requires, I think, an American of brains and breeding, a compatriot of the nomad. It has occurred to me that you are equipped by a habit of courtesy and tact to--arrive accidentally in the path of the caravan--" "I thank you!" said Philip dryly. "I prefer," he added stiffly, "to confine my diplomatic activities to more conventional channels." "When I assure you," purred the Baron with his maddening precision of speech, "that this information is of peculiar value to me and without immediate significance to the lady herself, I am sure that you will not feel bound to withhold your--hum--your cooeperation in so slight a personal inconvenience, singular as it may all seem to you, I am right?" Philip reddened uncomfortably. "I am to understand that I would undertake this peculiar mission equipped with no further information than you have offered?" "Exactly so," said the Baron. "I must beg of you to undertake it without question." "Pray believe," flashed Philip, "that I am not inclined to question. That fact," he added coldly, "is in itself a handicap." "The lady's name," explained the Baron quietly, "is Westfall--Diane Westfall." "Impossible!" exclaimed Philip and savagely bit his lip. "Ah, then you know the lady!" said the Baron softly. "I regret," said Philip formally, "that I have not had the honor of meeting Miss Westfall." But he saw vividly again a girl straight and slender as a silver birch, with firm, wind-bright skin and dark, mocking eyes. There were hemlocks and a dog--and Dick Sherrill had been talkative over billiards the night before. "Miss Westfall," added Philip guilelessly, "is the owner of the Glade Farm below here in the valley."
