There was, until a year ago, a little and very grimy-looking shop near Seven Dials, over which, in weather-worn yellow lettering, the name of "C. Cave, Naturalist and Dealer in Antiquities," was inscribed. The contents of its window were curiously variegated. They comprised some elephant tusks and an imperfect set of chessmen, beads and weapons, a box of eyes, two skulls of tigers and one human, several moth-eaten stuffed monkeys (one holding a lamp), an old-fashioned cabinet, a flyblown ostrich egg or so, some fishing-tackle, and an extraordinarily dirty, empty glass fish-tank. There was also, at the moment the story begins, a mass of crystal, worked into the shape of an egg and brilliantly polished. And at that two people, who stood outside the window, were looking, one of them a tall, thin clergyman, the other a black-bearded young man of dusky complexion and unobtrusive costume. The dusky young man spoke with eager gesticulation, and seemed anxious for his companion to purchase the article.

While they were there, Mr. Cave came into his shop, his beard still wagging with the bread and butter of his tea. When he saw these men and the object of their regard, his countenance fell. He glanced guiltily over his shoulder, and softly shut the door. He was a little old man, with pale face and peculiar watery blue eyes; his hair was a dirty grey, and he wore a shabby blue frock coat, an ancient silk hat, and carpet slippers very much down at heel. He remained watching the two men as they talked. The clergyman went deep into his trouser pocket, examined a handful of money, and showed his teeth in an agreeable smile. Mr. Cave seemed still more depressed when they came into the shop.
