A moment's reflection, however, sufficed to save the ingenuous young man from the pitfall of so serious a social solecism. It would be fatal to accost him. For, mark you, no matter how gentlemanly and well-tailored a stranger may look, you can never be sure nowadays (in these topsy-turvy times of subversive radicalism) whether he is or is not really a gentleman. That makes acquaintanceship a dangerous luxury. If you begin by talking to a man, be it ever so casually, he may desire to thrust his company upon you, willy-nilly, in future; and when you have ladies of your family living in a place, you really CANNOT be too particular what companions you pick up there, were it even in the most informal and momentary fashion. Besides, the fellow might turn out to be one of your social superiors, and not care to know you; in which case, of course, you would only be letting yourself in for a needless snubbing. In fact, in this modern England of ours, this fatherland of snobdom, one passes one's life in a see-saw of doubt, between the Scylla and Charybdis of those two antithetical social dangers. You are always afraid you may get to know somebody you yourself do not want to know, or may try to know somebody who does not want to know you. Guided by these truly British principles of ancestral wisdom, Philip Christy would probably never have seen anything more of the distinguished-looking stranger had it not been for a passing accident of muscular action, over which his control was distinctly precarious. He happened in brushing past to catch the stranger's eye. It was a clear blue eye, very deep and truthful. It somehow succeeded in riveting for a second Philip's attention. And it was plain the stranger was less afraid of speaking than Philip himself was. For he advanced with a pleasant smile on his open countenance, and waved one gloveless hand in a sort of impalpable or half-checked salute, which impressed his new acquaintance as a vaguely polite Continental gesture. This affected Philip favourably: the newcomer was a somebody then, and knew his place: for just in proportion as Philip felt afraid to begin conversation himself with an unplaced stranger, did he respect any other man who felt so perfectly sure of his own position that he shared no such middle-class doubts or misgivings. A duke is never afraid of accosting anybody. Philip was strengthened, therefore, in his first idea, that the man in the grey suit was a person of no small distinction in society, else surely he would not have come up and spoken with such engaging frankness and ease of manner.
