It was my first visit to the scene of the crime⁠—a high, dingy, narrow-chested house, prim, formal, and solid, like the century which gave it birth. Lestrade’s bulldog features gazed out at us from the front window, and he greeted us warmly when a big constable had opened the door and let us in. The room into which we were shown was that in which the crime had been committed, but no trace of it now remained save an ugly, irregular stain upon the carpet. This carpet was a small square drugget in the centre of the room, surrounded by a broad expanse of beautiful, old-fashioned wood-flooring in square blocks, highly polished. Over the fireplace was a magnificent trophy of weapons, one of which had been used on that tragic night. In the window was a sumptuous writing-desk, and every detail of the apartment, the pictures, the rugs, and the hangings, all pointed to a taste which was luxurious to the verge of effeminacy.

“Seen the Paris news?” asked Lestrade.

Holmes nodded.
