"He held out the coffee-pot engagingly towards the small gentleman who thereupon laid the watch down tenderly removed the eye-glass from his eye and smiled. And I found Mr. Polton's smile almost as astonishing as the other gentleman's vocabulary. It was the most amazingly wrinkly smile that I have ever seen but yet singularly genial and pleasant. And here I may remark that this amiable little gentleman was for some time a profound mystery to me. I could make nothing of him. I could not place him socially or otherwise. By his appearance he might in different raiment have been a dignitary of the Church. His deferential manner suggested some superlative kind of manservant but his hands and his comprehensive and inexhaustible knowledge of the products of the ancient crafts hinted at the dealer or expert collector. It was only after I had known him some months that the mystery was resolved through the medium of a legal friend as will be related in due course."
