'Have you yet paid a visit to Wembley, Charles?' he asked. 'No? Precisely as I suspected. Well, that is the mission on which I am here this afternoon. Honoria wishes me to take you to Wembley. She says it will broaden your mind, in which view I am at one with her. We will start immediately after luncheon.'

Biffy cast an imploring look at me.

'You'll come too, Bertie?'

There was such agony in his eyes that I only hesitated for a second. A pal is a pal. Besides, I felt that, if only the bulb fulfilled the high expectations I had formed of it, the merry expedition would be cancelled in no uncertain manner.

'Oh, rather,' I said.

'We must not trespass on Mr Wooster's good nature,' said Sir Roderick, looking pretty puff-faced.

'Oh, that's all right,' I said. 'I've been meaning to go to the good old exhibish for a long time. I'll slip home and change my clothes and pick you up here in my car.'

There was a silence. Biffy seemed too relieved at the thought of not having to spend the afternoon alone with Sir Roderick to be capable of speech, and Sir Roderick was registering silent disapproval. And then he caught sight of the bouquet by Biffy's plate.

'Ah, flowers,' he said. 'Sweet peas, if I am not in error. A charming plant, pleasing alike to the eye and the nose.'

I caught Biffy's eye across the table. It was bulging, and a strange light shone in it.
