He held out his snuffbox of old gold, with a great amethyst in the centre of the lid. Its splendour was in such contrast to his homely ways and simple life that I could not help commenting upon it.

"Ah," said he, "I forgot that I had not seen you for some weeks. It is a little souvenir from the King of Bohemia in return for my assistance in the case of the Irene Adler papers."

"And the ring?" I asked, glancing at a remarkable brilliant which sparkled upon his finger.

"It was from the reigning family of Holland, though the matter in which I served them was of such delicacy that I cannot confide it even to you, who have been good enough to chronicle one or two of my little problems."

"And have you any on hand just now?" I asked with interest.

"Some ten or twelve, but none which present any feature of interest. They are important, you understand, without being interesting. Indeed, I have found that it is usually in unimportant matters that there is a field for the observation, and for the quick analysis of cause and effect which gives the charm to an investigation. The larger crimes are apt to be the simpler, for the bigger the crime the more obvious, as a rule, is the motive. In these cases, save for one rather intricate matter which has been referred to me from Marseilles, there is nothing which presents any features of interest. It is possible, however, that I may have something better before very many minutes are over, for this is one of my clients, or I am much mistaken."

He had risen from his chair and was standing between the parted blinds gazing down into the dull neutral-tinted London street. Looking over his shoulder, I saw that on the pavement opposite there stood a large woman with a heavy fur boa round her neck, and a large curling red feather in a broad-brimmed hat which was tilted in a coquettish Duchess of Devonshire fashion over her ear. From under this great panoply she peeped up in a nervous, hesitating fashion at our windows, while her body oscillated backward and forward, and her fingers fidgeted with her glove buttons. Suddenly, with a plunge, as of the swimmer who leaves the bank, she hurried across the road, and we heard the sharp clang of the bell.

"I have seen those symptoms before," said Holmes, throwing his cigarette into the fire. "Oscillation upon the pavement always means an affaire de coeur. She would like advice, but is not sure that the matter is not too delicate for communication. And yet even here we may discriminate. When a woman has been seriously wronged by a man she no longer oscillates, and the usual symptom is a broken bell wire. Here we may take it that there is a love matter, but that the maiden is not so much angry as perplexed, or grieved. But here she comes in person to resolve our doubts."
