of minute observation have enabled him to prove conclusively

that the miscreants could not have entered by the door or by

the window but must have made their way across the roof of

the building, and so through a trapdoor into a room which

communicated with that in which the body was found. This

fact, which has been very clearly made out, proves conclusively that it was no mere haphazard burglary. The prompt

and energetic action of the officers of the law shows the

great advantage of the presence on such occasions of a

single vigorous and masterful mind. We cannot but think

that it supplies an argument to those who would wish to see

our detectives more decentralized, and so brought into closer

and more effective touch with the cases which it is their

duty to investigate.

“Isn’t it gorgeous!” said Holmes, grinning over his coffee cup. “What do you think of it?”

“I think that we have had a close shave ourselves of being arrested for the crime.”

“So do I. I wouldn’t answer for our safety now if he should happen to have another of his attacks of energy.”

At this moment there was a loud ring at the bell, and I could hear Mrs. Hudson, our landlady, raising her voice in a wail of expostulation and dismay.

“By heavens, Holmes,” I said, half rising, “I believe that they are really after us.”

“No, it’s not quite so bad as that. It is the unofficial force — the Baker Street irregulars.”

As he spoke, there came a swift pattering of naked feet upon the stairs, a clatter of high voices, and in rushed a dozen dirty and ragged little street Arabs. There was some show of discipline among them, despite their tumultuous entry, for they instantly drew up in line and stood facing us with expectant faces. One of their number, taller and older than the others, stood forward with an air of lounging superiority which was very funny in such a disreputable little scarecrow.

“Got your message, sir,” said he, “and brought ’em on sharp. Three bob and a tanner for tickets.”

“Here you are,” said Holmes, producing some silver. “In future they can report to you, Wiggins, and you to me. I cannot have the house invaded in this way. However, it is just as well that you should all hear the instructions. I want to find the whereabouts of a steam launch called the Aurora, owner Mordecai Smith, black with two red streaks, funnel black with a white band. She is down the river somewhere. I want one boy to be at Mordecai Smith’s landing-stage opposite Millbank to say if the boat comes back. You must divide it out among yourselves and do both banks thoroughly. Let me know the moment you have news. Is that all clear?”

“Yes, guv’nor,” said Wiggins.

“The old scale of pay, and a guinea to the boy who finds the boat. Here’s a day in advance. Now off you go!”

He handed them a shilling each, and away they buzzed down the stairs, and I saw them a moment later streaming down the street.
