Iâd bet my boots on it.â
âThen whereâs the stone that I saw?â asked Captain Brock, tapping himself in the chest with an angry finger. âWhere did that go?â
âSimple, Captain Brock,â said Theodore, taking out a handkerchief with a flourish. âThe stone inside this box was designed to disintegrate, and here,â he added, picking out something from inside, âis the proof.â The Curator, Captain Brock, and the Inspector leaned in to get a closer look. Pinched in the folds of Theodoreâs handkerchief was a gleaming shard.
âWell, I never,â said Inspector Lemone. âIf you havenât done it again, Goodman!â
âDone what?â said a small voice behind them. âHave I missed much? No matter. Just carry on as you were.â Everyone turned around. Wilma waved at them. âOnly me,â she said, and grinned. âCame in inside a big dinosaurâs skull. It was quite cramped. But he liked it,â she added as Pickle licked his lips.
âNo, no, no,â said Theodore with a frown. âThis wonât do. Wilma, does Mrs. Waldock know that youâre here?â
âIf I said not really, would that be a problem?â said Wilma, twisting the edge of her pinafore in her fingers.
The detective fixed her with a serious stare that left Wilma in no doubt that she might be in considerable trouble. âI shall have to take you back when Iâm done,â he said. âNow stay close to Inspector Lemone and not one peep out of you. Do you understand?â Wilma nodded and smiled up at the Inspector.
Captain Brock had taken Theodoreâs handkerchief and was holding the shard to the light. Wilma gasped a little as she saw it. âItâs like sunshine,â she said.
âNot one peep, remember?â said Inspector Lemone, putting a finger to his lips.
âWhat is it, Goodman?â asked the Captain, squinting at the sparkling object. âAnd how did it disintegrate?â
âLook inside the box, Captain,â said the detective, holding it out for everyone to see. âThereâs a tiny hole in one side. The clasp of the box was designed in such a way so as to release a melting agent when the box was shut. It is my belief that the fake Katzin Stone was made of nothing more than colored sugar, and that when the box was closed a concentrated gas or liquid simply melted it away.â
âDevilish simple,â said Miss Pagne, smiling a little.
âSo the person who took it,â said Wilma, wide-eyed, âmust have swapped the stone! Or swapped the box! Like in that magic trick when you were solving the Case of the Vanished Buttons. Iâve got it on my Clueââ
âShhhhhh, Wilma,â whispered the Inspector, giving her a nudge.
âSheâs quite right,â acknowledged Theodore, raising an eyebrow, âif a little overexcitable . . . so we may be looking for someone with an exceptional ability for sleight of hand.â
âThough why swap it for a stone that melted?â asked the Curator, shooting Wilma a sideways glance.
âExcept for that shard. And thank goodness for it. By examining it I shall be able to determine exactly what itâs made of. When I understand that Iâll be nearer to knowing who made it. Clearly whoever it was wanted something that would leave no traceâbut buy him some time.â
âBut what about the real Katzin Stone, Mr. Goodman?â said the Curator, tapping his cane on the floor. âItâs all very well you chasing theories, but the most precious jewel ever found is still missing. And I want to know what youâre going to do about it.â He took a step forward to emphasize his point and, catching his foot on the edge of one of the display cases, slipped a little and fell against the Captain. The gleaming shard, the detectiveâs only clue, flew out of the soldierâs hand and into the gloom of
