Thorndyke turned and looked at him in cold distaste.
“Since the creation of the instrument, no doubt. Certainly since it came to me by inheritance.”
“By inheritance?” said the younger man, with deliberate doubt in his intonation. “I think, Mr. Thorndyke, that your uncle, who bears the same name as yourself, would give a different version of the way you acquired this costly possession.”
Thorndyke started violently.
“Do you mean to insult me?” he said in almost a whisper, guilt written in his face.
Kathleen, spell-bound by Colin’s stern looks, held the violin breathlessly.
“I mean, Mr. Thorndyke, to make absolutely no fuss in this very unpleasant matter. But I mean also to make it perfectly plain to you that I know all about this Stradivarius with the mark of a hand pointing. I am informed when and how it was taken out of your uncle Thorndyke’s trunk in his boarding-house. And if you will give it up to him quietly, I shall not say another word to any one concerning it.”
“An ingenious method to possess yourself of a valuable piece of property,” sneered Thorndyke, now livid with fear and rage.
“I have this to offer in exchange,” said Colin, controlling himself perfectly, as he took out the scarabeus and held it, together with the old man’s written order for the violin, for the inspection of the thief.
