‘But Lawson had a revolver?’

‘Yes.’

‘And was threatening your husband with it?’

‘Yes. But he didn’t mean it.’

Inspector Curry felt his usual slight exasperation at this statement. So she was another of them!

‘You can’t possibly have been sure of that, Mrs Serrocold.’

‘Well, but I was sure. In my own mind, I mean. What is it the young people say — putting on an act? That’s what I felt it was. Edgar’s only a boy. He was being melodramatic and silly and fancying himself as a bold desperate character. Seeing himself as the wronged hero in a romantic story. I was quite sure he would never fire that revolver.’

‘But he did fire it, Mrs Serrocold.’

Carrie Louise smiled.

‘I expect it went off by accident.’

Again exasperation mounted in Inspector Curry.

‘It was not an accident. Lawson fired that revolver twice — and fired it at your husband. The bullets only just missed him.’

Carrie Louise looked startled and then grave.

‘I can’t really believe that. Oh yes’ — she hurried on to forestall the Inspector’s protest — ‘of course I have to believe it if you tell me so. But I still feel there must be a simple explanation. Perhaps Dr Maverick can explain it to me.’

‘Oh yes, Dr Maverick will explain it all right,’ said Curry grimly. ‘Dr Maverick can explain anything. I’m sure of that.’

Unexpectedly Mrs Serrocold said:

‘I know that a lot of what we do here seems to you foolish and pointless, and psychiatrists can be very irritating sometimes. But we do achieve results, you know. We have our failures, but we have successes too. And what we try to do is worth doing. And though you probably won’t believe it, Edgar is really devoted to my husband. He started this silly business about Lewis’s being his father because he wants so much to have a father like Lewis. But what I can’t understand is why he should suddenly get violent. He had been so very much better — really practically normal. Indeed he has always seemed normal to me.’

The Inspector did not argue the point.

He said: ‘The revolver that Edgar Lawson had was one belonging to your granddaughter’s husband. Presumably Lawson took it from Walter Hudd’s room. Now tell me, have you ever seen this weapon before?’

On the palm of his hand he held out the small black automatic.

Carrie Louise looked at it.

‘No, I don’t think so.’

‘I found it in the piano stool. It has recently been fired. We haven’t had time to check on it fully yet, but I should say that it is almost certainly the weapon with which Mr Gulbrandsen was shot.’

She frowned.

‘And you found it in the piano stool?’

‘Under some very old music. Music that I should say had not been played for years.’

‘Hidden, then?’

‘Yes. You remember who was at the piano last night?’

‘Stephen Restarick.’

‘He was playing?’

‘Yes. Just softly. A funny melancholy little tune.’
