The Classic Mystery Collection - Arthur Conan Doyle [618]
"Surely," said Underhill, "Sherlock Holmes would say that he went by a logical rule."
"He may be right," answered the other; "but I mean a collective rule. It's like the staff work of an army. We pool our information."
"And you don't think detective stories allow for that?" asked his friend.
"Well, let's take any imaginary case of Sherlock Holmes, and Lestrade, the official detective. Sherlock Holmes, let us say, can guess that a total stranger crossing the street is a foreigner, merely because he seems to look for the traffic to go to the right instead of the left. I'm quite ready to admit Holmes might guess that. I'm quite sure Lestrade wouldn't guess anything of the kind. But what they leave out is the fact that the policeman, who couldn't guess, might very probably know. Lestrade might know the man was a foreigner merely because his department has to keep an eye on all foreigners; some would say on all natives, too. As a policeman I'm glad the police know so much; for every man wants to do his own job well. But as a citizen, I sometimes wonder whether they don't know too much."
"You don't seriously mean to say," cried Underhill incredulously, "that you know anything about strange people in a strange street. That if a man walked out of that house over there, you would know anything about him?"
"I should if he was the householder," answered Bagshaw. "That house is rented by a literary man of Anglo-Roumanian extraction, who generally lives in Paris, but is over here in connexion with some poetical play of his. His name's Osric Orm, one of the new poets, and pretty steep to read, I believe."
"But I mean all the people down the road," said his companion. "I was thinking how strange and new and nameless everything looks, with these high blank walls and these houses lost in large gardens. You can't know all of them."
"I know a few," answered Bagshaw. "This garden wall we're walking under is at the end of the grounds of Sir Humphrey Gwynne, better known as Mr. Justice Gwynne, the old judge who made such a row about spying during the war. The house next door to it belongs to a wealthy cigar merchant. He comes from Spanish-America and looks very swarthy and Spanish himself; but he bears the very English name of Buller. The house beyond that--did you hear that noise?"
"I heard something," said Underhill, "but I really don't know what it was."
"I know what it was," replied the detective, "it was a rather heavy revolver, fired twice, followed by a cry for help. And it came straight out of the back garden of Mr. Justice Gwynne, that paradise of peace and legality."
He looked up and down the street sharply and then added:
"And the only gate of the back garden is half a mile round on the other side. I wish this wall were a little lower, or I were a little lighter; but it's got to be tried."
"It is lower a little farther on," said Underhill, "and there seems to be a tree that looks helpful."
They moved hastily along and found a place where the wall seemed to stoop abruptly, almost as if it had half-sunk into the earth; and a garden tree, flamboyant with the gayest garden blossom, straggled out of the dark enclosure and was gilded by the gleam of a solitary street- lamp. Bagshaw caught the crooked branch and threw one leg over the low wall; and the next moment they stood knee-deep amid the snapping plants of a garden border.
The garden of Mr. Justice Gwynne by night was rather a singular spectacle. It was large and lay on the empty edge of the suburb, in the shadow of a tall, dark house that was the last in its line of houses. The house was literally dark, being shuttered and unlighted, at least on the side overlooking the garden.
