Holmes’s cold, thin fingers closed round my wrist and led me forwards down a long hall, until I dimly saw the murky fanlight over the door. Here Holmes turned suddenly to the right, and we found ourselves in a large, square, empty room, heavily shadowed in the corners, but faintly lit in the centre from the lights of the street beyond. There was no lamp near and the window was thick with dust, so that we could only just discern each other’s figures within. My companion put his hand upon my shoulder and his lips close to my ear.
'Do you know where we are?' he whispered.
Sherlock’s seduction techniques involve a lot of dark rooms and close whispering.
