‘Our Hattie asked her that? I don’t believe it for a moment.’

‘Why don’t you believe it, Mr Weyman?’

‘It’s not like her. Not the sort of thing she’d think of or bother about. Dear Lady Stubbs’ mind revolves entirely round herself.’

‘I’m still waiting, Mr Weyman, for your answer to my question.’

‘Where I was between four-fifteen and five o’clock? Well, really, Inspector, I can’t say off-hand. I was about – if you know what I mean.’

‘About where?’

‘Oh, here and there. I mingled a bit on the lawn, watched the locals amusing themselves, had a word or two with the fluttery film star. Then, when I got sick of it all, I went along to the tennis court and mused over the design for the Pavilion. I also wondered how soon someone would identify the photograph that was the first clue for the Murder Hunt with a section of tennis net.’

‘Did someone identify it?’

‘Yes, I believe someone did come along, but I wasn’t really noticing by then. I got a new idea about the Pavilion – a way of making the best of two worlds. My own and Sir George’s.’

‘And after that?’

‘After that? Well, I strolled around and came back to the house. I strolled down the quay and had a crack with old Merdell, then came back. I can’t fix any of the times with any accuracy. I was, as I said, in the first place, about! That’s all there is to it.’

‘Well, Mr Weyman,’ said the inspector briskly, ‘I expect we can get some confirmation of all this.’

‘Merdell can tell you that I talked to him on the quay. But of course that’ll be rather later than the time you’re interested in. Must have been after five when I got down there. Very unsatisfactory, isn’t it, Inspector?’

‘We shall be able to narrow it down, I expect, Mr Weyman.’

The inspector’s tone was pleasant, but there was a steely ring in it that did not escape the young architect’s notice. He sat down on the arm of a chair.

‘Seriously,’ he said, ‘who can have wanted to murder that girl?’

‘You’ve no ideas yourself, Mr Weyman?’

‘Well, off-hand, I’d say it was our prolific authoress, the Purple Peril. Have you seen her imperial purple getup? I suggest that she went a bit off her onion and thought how much better the Murder Hunt would be if there was a real body. How’s that?’

‘Is that a serious suggestion, Mr Weyman?’

‘It’s the only probability I can think of.’

‘There’s one other thing I would like to ask you, Mr Weyman. Did you see Lady Stubbs during the course of the afternoon?’

‘Of course I saw her. Who could miss her? Dressed up like a mannequin of Jacques Fath or Christian Dior?’

‘When did you see her last?’
