THERE is nothing so deceptive as a half-truth. The half that is true has a certain suggestive power that lends to the other half a plausibility and a credibility that it does not possess in its own right. This interesting psychological fact was realized, at least subconsciously, by Mr. Didbury Toke. For Mr. Toke was a collector of antique and other works of art, a connoisseur and a dealer. He really was. It was not a pose or a pretence. He was a bona fide collector, and a connoisseur who had that genuine love of fine and beautiful works that is the indispensable condition of real connoisseurship. But Mr. Toke was also a fence. And that was where the illusory element came in. Any person who, not being a known collector and a recognized dealer, should have been seen, as he frequently was, in the company of definitely shady characters, would inevitably have attracted the attention of the guardians of the law.
