Miss Gainsford made her entrance with a Mayfairish gallantry that was singularly dated. Alleyn wondered if she had decided that her first reading of her new role was mistaken. ‘She’s abandoned the brave little woman for the suffering mondaine who goes down with an epigram,’ he thought and sure enough Miss Gainsford addressed herself to him with staccato utterance and brittle highhandedness.

‘Ought one to be terribly flattered because one is the first to be grilled?’ she asked. ‘Or is it a sinister little hint that one is top of the suspect list?’

‘As you don’t have to change,’ Alleyn said, ‘I thought it would be convenient to see you first. Will you sit down, Miss Gainsford?’

She did so elaborately, gave herself a cigarette, and turned to PC Lamprey: ‘May one ask The Force for a light?’ she asked. ‘Or would that be against the rules?’

Alleyn lit her cigarette while his unhappy subordinate retired to the table. She turned in her chair to watch him. ‘Is he going to take me down and use it all in evidence against me?’ she asked. Her nostrils dilated, she raised her chin and added jerkily: ‘That’s what’s called the Usual Warning, isn’t it?’

‘A warning is given in police practice,’ Alleyn said as woodenly as possible, ‘if there is any chance that the person under interrogation will make a statement that is damaging to himself. Lamprey will note down this interview and if it seems advisable you will be asked, later on, to give a signed statement.’

‘If that was meant to be reassuring,’ said Miss Gainsford, ‘I can’t have heard it properly. Could we get cracking?’

‘Certainly. Miss Gainsford, you were in the greenroom throughout the performance. During the last interval you were visited by Mr J. G. Darcey and by your uncle. Do you agree that as the result of something the deceased said, Mr Darcey hit him on the jaw?’

She said: ‘Wasn’t it too embarrassing! I mean the Gorgeous Primitive Beast is one thing but one old gentleman banging another about is so utterly another. I’m afraid I didn’t put that very clearly.’

‘You agree that Mr Darcey hit Mr Bennington?’

‘But madly. Like a sledge-hammer. I found it so difficult to know what to say. There just seemed to be no clue to further conversation.’

‘It is the conversation before rather than after the blow that I should like to hear about, if you please.’

Alleyn had turned away from her and was looking at Jacko’s portrait of Poole. He waited for some moments before she said sharply, ‘I suppose you think because I talk like this about it I’ve got no feeling. You couldn’t be more at fault.’ It was as if she called his attention to her performance.

He said, without turning: ‘I assure you I hadn’t given it a thought. What did your uncle say that angered Mr Darcey?’
