At the end of the corridor I stopped and glanced into a large and extremely smelly kitchen. Piles of dirty dishes lay in untidy stacks. Cheese and meat lay flyblown on the kitchen table. A bloated insect buzzed past my ear. One step in, the stink was overpowering. Behind me I heard Inge cough so that it was almost a retch. I hurried to the window and pushed it open. For a moment we stood there, enjoying the clean air. Then, looking down at the floor, I saw some papers in front of the stove. One of the doors to the incinerator was open, and I bent forward to take a look. Inside, the stove was full of burnt paper, most of it nothing more than ash; but here and there were the edges or corners of something that had not quite been consumed by the flames.

‘See if you can salvage some of this,’ I said. ‘It looks like someone was in a hurry to cover his tracks.’

‘Anything in particular?’

‘Anything legible, I suppose.’ I walked over to the kitchen doorway.

‘Where will you be?’

‘I’m going to take a look upstairs.’ I pointed to the dumb-waiter. ‘If you need me, just shout up the shaft there.’ She nodded silently, and rolled up her sleeves.

Upstairs, and on the same level as the front door, there was even more mess. Behind the front desk were empty drawers, their contents lying on the threadbare carpet; and the doors of every cupboard had been wrenched off their hinges. I was reminded of the mess in Goering’s Derfflingerstrasse apartment. Most of the bedroom floorboards had been ripped up, and some of the chimneys showed signs of having been probed with a broom. Then I went into the dining room. Blood had spattered the white wallpaper like an enormous graze, and on the rug was a stain the size of a dinner-plate. I stood on something hard, and bent down to pick up what looked like a bullet. It was a lead weight, encrusted with blood. I tossed it in my hand and then put it in my jacket pocket.
