Sir Arthur Conan Doyle: A Study in Scarlet

PART I. 3. CHAPTER III. THE LAURISTON GARDENS MYSTERY (continued)

"Nothing else? Is there no circumstance on which this whole case appears to hinge? Will you not telegraph again?"

"I have said all I have to say," said Gregson, in an offended voice.

Sherlock Holmes chuckled to himself, and appeared to be about to make some remark, when Lestrade, who had been in the front room while we were holding this conversation in the hall, reappeared upon the scene, rubbing his hands in a pompous and self-satisfied manner.

"Mr. Gregson," he said, "I have just made a discovery of the highest importance, and one which would have been overlooked had I not made a careful examination of the walls."

The little man's eyes sparkled as he spoke, and he was evidently in a state of suppressed exultation at having scored a point against his colleague.

"Come here," he said, bustling back into the room, the atmosphere of which felt clearer since the removal of its ghastly inmate. "Now, stand there!"

He struck a match on his boot and held it up against the wall.

"Look at that!" he said, triumphantly.

I have remarked that the paper had fallen away in parts. In this particular corner of the room a large piece had peeled off, leaving a yellow square of coarse plastering. Across this bare space there was scrawled in blood-red letters a single word --

RACHE.

"What do you think of that?" cried the detective, with the air of a showman exhibiting his show. "This was overlooked because it was in the darkest corner of the room, and no one thought of looking there. The murderer has written it with his or her own blood. See this smear where it has trickled down the wall! That disposes of the idea of suicide anyhow. Why was that corner chosen to write it on? I will tell you. See that candle on the mantelpiece. It was lit at the time, and if it was lit this corner would be the brightest instead of the darkest portion of the wall."
