"That is a detail which I shall speedily supply."
Lord St. Simon shook his head. "I am afraid that it will take wiser heads than yours or mine," he remarked, and bowing in a stately, old-fashioned manner he departed.
"It is very good of Lord St. Simon to honour my head by putting it on a level with his own," said Sherlock Holmes, laughing. "I think that I shall have a whisky and soda and a cigar after all this cross-questioning. I had formed my conclusions as to the case before our client came into the room."
"My dear Holmes!"
"I have notes of several similar cases, though none, as I remarked before, which were quite as prompt. My whole examination served to turn my conjecture into a certainty. Circumstantial evidence is occasionally very convincing, as when you find a trout in the milk, to quote Thoreau's example."
"But I have heard all that you have heard."
"Without, however, the knowledge of pre-existing cases which serves me so well. There was a parallel instance in Aberdeen some years back, and something on very much the same lines at Munich the year after the Franco-Prussian War. It is one of these cases–but, hullo, here is Lestrade! Good-afternoon, Lestrade! You will find an extra tumbler upon the sideboard, and there are cigars in the box."
The official detective was attired in a pea-jacket and cravat, which gave him a decidedly nautical appearance, and he carried a black canvas bag in his hand. With a short greeting he seated himself and lit the cigar which had been offered to him.
"What's up, then?" asked Holmes with a twinkle in his eye. "You look dissatisfied."
"And I feel dissatisfied. It is this infernal St. Simon marriage case. I can make neither head nor tail of the business."
"Really! You surprise me."
"Who ever heard of such a mixed affair? Every clue seems to slip through my fingers. I have been at work upon it all day."
"And very wet it seems to have made you," said Holmes laying his hand upon the arm of the pea-jacket.
"Yes, I have been dragging the Serpentine."
