"How d'ye do?" responded Mr. Prohack with just as much calmness and perhaps ten per cent less geniality. Mr. Prohack was a peculiar fellow, and that on this occasion he gave rather less geniality than he received was due to the fact that he had never before spoken to the cupid in his life and that he was wondering whether membership of the same club entirely justified so informal a mode of address--without an introduction and outside the club premises. For, like all modest men, Mr. Prohack had some sort of a notion of his own dignity, a sort of a notion that occasionally took him quite by surprise. Mr. Prohack did not even know the surname of his aggressor. He only knew that he never overheard other men call him anything but "Ozzie." Had not Mr. Prohack been buried away all his life in the catacombs of the Treasury and thus cut off from the great world-movement, he would have been fully aware that Oswald Morfey was a person of importance in the West End of London, that he was an outstanding phenomenon of the age, that he followed very closely all the varying curves of the great world-movement, that he was constantly to be seen on the pavements of Piccadilly, Bond Street, St. James's Street, Pall Mall and Hammersmith, that he was never absent from a good first night or a private view of very new or very old pictures or a distinguished concert or a poetry-reading or a fashionable auction at Christie's, that he received invitations to dinner for every night in the week and accepted all those that did not clash with the others, that in return for these abundant meals he gave about once a month a tea-party in his trifling Japanese flat in Bruton Street, where the sandwiches were as thin as the sound of the harpsichord which eighteenth century ladies played at his request; and that he was in truth what Mr. Asprey Chown called "social secretary" to Mr. Asprey Chown.
