Had it occurred to a stranger who gazed for the first time upon Mr. and Miss Fox-Cordery, as they sat in the living-room of the Fox-Cordery establishment, that for some private reason the brother and sister had dressed in each other's clothes, he might well have been excused the fancy. It was not that the lady was so much like a gentleman, but that the gentleman was so much like a lady; and a closer inspection would certainly have caused the stranger to do justice at least to Miss Fox-Cordery. She was the taller and stouter of the twain, and yet not too tall or stout for grace and beauty of an attractive kind. There was some color in her face, his was perfectly pallid, bearing the peculiar hue observable in waxwork figures; her eyes were black, his blue; her hair was brown, his sandy; and the waxwork suggestion was strengthened by his whiskers and mustache, which had a ludicrous air of having been stuck on. There was a cheerful energy in her movements which was conspicuously absent in his, and her voice had a musical ring in it, while his was languid and deliberate. She was his junior by a good ten years, her age being twenty-eight, but had he proclaimed himself no more than thirty, only those who were better informed would have disputed the statement. When men and women reach middle age the desire to appear younger than they are is a pardonable weakness, and it was to the advantage of Mr. Fox-Cordery that it was less difficult for him than for most of us to maintain the harmless fiction. This was not the only bubble which Mr. Fox-Cordery was ready to encourage in order to deceive the world. His infantile face, his appealing blue eyes, his smooth voice, were traps which brought many unwary persons to grief. Nature plays numberless astonishing tricks, but few more astonishing than that which rendered the contrast between the outer and inner Mr. Fox-Cordery even more startling than that which existed in the physical characteristics of this brother and sister.
