I grabbed him by the armpits and went backwards down the stairs to the laboratory. His feet bounced from tread to tread in a staccato rhythm that matched my own unsteady descent, thumping and banging around the narrow stairwell. Our shadows danced on the walls. Blood was still flowing, all sticky, seeping from the soaking wet towel, rapidly forming drips on the silk lapels, then disappearing into the folds of the jacket, like trails of slightly glinting snot side-tracked by the slightest roughness in the fabric, sometimes accumulating into drops that fell to the floor and exploded into star-shaped stains. I let him slump at the bottom of the stairs, right next to the laboratory door, and then went back up to fetch the razor and to mop up the bloodstains before Otto returned. But Otto came in by the other door at almost the same time as I did. He looked at me uncomprehendingly. I beat a retreat, ran down the stairs, and shut myself in the laboratory. I padlocked the door and jammed the wardrobe up against it.
