We waited in the library. It wasn’t big by the standards of a Bismarck or a Hindenburg, and you couldn’t have packed more than six cars between the Reichstag-sized desk and the door. It was decorated in early Lohengrin, with its great beams, granite chimney-piece in which a log crackled quietly, and wall-mounted weaponry. There were plenty of books, of the sort you buy by the metre: lots of German poets and philosophers and jurists with whom I can claim a degree of familiarity, but only as the names of streets and cafés and bars.

I took a hike around the room. ‘If I’m not back in five minutes, send out a search party.’

Schemm sighed and sat down on one of the two leather sofas that were positioned at right angles to the fire. He picked a magazine off the rack and pretended to read. ‘Don’t these little cottages give you claustrophobia?’ Schemm sighed petulantly, like an old maiden aunt catching the smell of gin on the pastor’s breath.

‘Do sit down, Herr Gunther,’ he said.

I ignored him. Fingering the two hundreds in my trouser pocket to help me stay awake, I meandered over to the desk and glanced over its green-leather surface. There was a copy of the Berliner Tageblatt, well read, and a pair of half-moon spectacles; a pen; a heavy brass ashtray containing the butt of a well-chewed cigar and, next to it, the box of Black Wisdom Havanas from which it had been taken; a pile of correspondence and several silver-framed photographs. I glanced over at Schemm, who was making heavy weather of his magazine and his eyelids, and then picked up one of the framed photographs. She was dark and pretty, with a full figure, which is just how I like them, although I could tell that she might find my after-dinner conversation quite resistible: her graduation robes told me that.

‘She’s beautiful, don’t you think?’ said a voice that came from the direction of the library door and caused Schemm to get up off the sofa. It was a singsong sort of voice with a light Berlin accent. I turned to face its owner and found myself looking at a man of negligible stature. His face was florid and puffy and had something so despondent in it that I almost failed to recognize it. While Schemm was busy bowing I mumbled something complimentary about the girl in the photograph.
