I was standing far in the background, at a window opposite the door, while the others were grouped together more in the foreground; and what I saw was a very tall man (so tall that he could dwarf Eagle March's five foot ten almost to insignificance), six foot two, perhaps, and--not stout yet, but showing signs that one day he might become so. I noticed that he held himself magnificently, his broad shoulders thrown back, his head up; and that he walked with a slight swagger, more like a cavalryman than an officer in the artillery. Perhaps it was the electric light which made his skin look as white as Diana's, without a touch of the tan that darkened Eagle March's fairer complexion; but the white was of a different quality, somehow, from Diana's. Hers is pearl white; his had the thick, untranslucent look which pale Jewish faces have. I didn't know then that Sidney Vandyke was of Hebrew blood, but afterward I heard that his mother had Spanish Jews for ancestors on one side, and that with her came most of the family money. He was in full dress uniform, which became him splendidly; and I had a glimpse of a rather large face, drawn with square, straight lines that gave it a relentless look; square white forehead; straight black brows; straight, short nose; large, squarely opened dark eyes, brilliant and self-confident; straight black moustache; thick, square red lips; square chin, and a full neck set on square shoulders. After that first glimpse I saw only the profile, for in meeting Kitty Main and being introduced to Di and Father, Major Vandyke had to turn half away from me. Even a profile, however, tells something; and when Major Vandyke began to talk to Di, bending down a little, I could see that he admired her very much, or else wanted to convey this impression to her mind.
