‘Oh, yes. They won’t have him in the army. He’s got something wrong with his eyes, and anyway he’s ranked as doing an essential job on the place. The police got the whole story out of Markins, of course,’ said Fabian, ‘and for want of a better suspect, concentrated on the boy. I expect he looms large in the files, doesn’t he?’

‘He peters out about halfway through.’

‘That’s because he’s the only member of the household who’s got a sort of alibi. We all heard him playing the piano until just before the diamond clip was found, which was at five to nine. When he’d just started, at eight o’clock it was, Markins saw him in the annexe, playing, and he never stopped for longer than half a minute or less. Incidentally, to the best of my belief, that’s the last time young Cliff played on the piano in the annexe, or on any other piano, for a matter of that. His mother, who was worried about him, went over to the annexe and persuaded him to return with her to the cottage. There he heard the nine o’clock news bulletin and listened to a programme of classical music.

‘You may think that was a bit thick,’ said Fabian. ‘I mean a bit too much in character with the sensitive young plant, but it’s what he did. The previous night you must remember he’d had a snorting row with Flossie, and followed it up with a sixteen-mile hike and no sleep. He was physically and emotionally exhausted and dropped off to sleep in his chair. His mother got him to bed and she and his father sat up until after midnight, talking about him. Before she turned in, Mrs Johns looked at young Cliff and found him fathoms deep. Even the detective-sergeant saw that Flossie would have returned by midnight if she’d been alive. Sorry, Ursy dear, I interrupt continually. We are back on the lawn. Cliff is playing Bach on a piano that misses on six notes and Flossie’s talking about the party in the shearing-shed. Carry on.’
