Last week, he stayed in a place full of moldy vouchers for three days in order to check old accounts from ten years ago. When he came out, he smelled of old dust. But this time, the smell was stronger, as if something had rotted under the hot summer sun, and the smell of earth mixed with it penetrated into the lungs.
