Holmes had sat up upon the couch, and I saw him motion like a man who is in need of air. A maid rushed across and threw open the window. At the same instant I saw him raise his hand and at the signal I tossed my rocket into the room with a cry of "Fire!" The word was no sooner out of my mouth than the whole crowd of spectators, well dressed and ill - gentlemen, ostlers, and servant maids - joined in a general shriek of "Fire!" Thick clouds of smoke curled through the room and out at the open window.
