"I thought you'd guess! There aren't many who'd make such an offer. Think what it would mean to me if it could be accepted, and I could have the handling of the money. There are three small pictures in the little octagon gallery next door, too, Van Vreck took a fancy to on a visit he paid us from Saturday to Monday last summer. We never thought much of them, and they're in a dark place, labelled in the catalogue 'Artist unknown: School of Fragonard'; but _he_ swore they were authentic Fragonards, and would have backed his opinion to the tune of fifteen thousand pounds for the trio, or six thousand for the one he liked best. Isn't it aggravating? In the Chinese room he went mad over some bits of jade, especially a Buddha nobody else had ever admired." "He's one of the few millionaire collectors who is really a judge of all sorts of things," Knight replied. "But, great Scott! I'm no expert, yet it strikes me these miniatures are something out of the ordinary!" "Well, yes, they are," Annesley-Seton admitted, modestly. "That queer one at the top is a Nicholas Hilliard. I believe he was the first of the miniaturists. And the two just underneath are Samuel Coopers. They say he stood at the head of the Englishmen. There are three Richard Cosways and rather a nice Angelica Kauffmann." "It was the Fragonard miniature Mr. Van Vreck liked best," put in Constance. "It seems he painted only a few. And next, the Goya----" "Good heavens! where is the Fragonard?" cried Dick, his eyes bulging behind his pince-nez. "Surely it was here----" "Oh, surely, yes!" panted his wife. "It was never anywhere else." For an instant they were stricken into silence, both staring at a blank space on the black velvet background where twenty-nine miniatures hung. There was no doubt about it when they had reviewed the rows of little painted faces. The Fragonard was gone. "Stolen!" gasped Lady Annesley-Seton. "Unless one of you, or some servant you trust with the key, is a somnambulist," said Knight. "I don't see how it would pay a thief to steal such a thing. It must be too well known. He couldn't dispose of it--that is if he weren't a collector himself; and even then he could never show it. But--by Jove!" "What is it? What have you seen?" Annesley-Seton asked, sharply. Knight pointed, without touching the cabinet. He had never come near enough to do that. "It looks to me as if a square bit of glass had been cut out on the side where the lost miniature must have hung," he said. "I can't be sure, from where I stand, because the cabinet is too close to the wall of the recess." Dick Annesley-Seton thrust his arm into the space between green brocade and glass, then slipped his hand through a neatly cut aperture just big enough to admit its passage. With his hand in the square hole he could reach the spot where the miniature had hung, and could have taken it off the hook had it been there. But hook, as well as miniature, was missing.
