'No, sir.'

The coroner doodled on the pad before him. Without looking at Cordelia, he said:

'And now, Miss Gray, will you please explain to the court how Sir Ronald came to have your gun.'

This was the difficult part, but Cordelia had rehearsed it. The Cambridge police had been very thorough. They had asked the same questions over and over again. She knew exactly how Sir Ronald had come to have the gun.

She remembered a piece of Dalgliesh dogma, reported by Bernie, which had seemed to her at the time more appropriate advice for a criminal than a detective. 'Never tell an unnecessary lie; the truth has great authority. The cleverest murderers have been caught, not because they told the one essential lie, but because they continued to lie about unimportant detail when the truth could have done them no harm.'

She said:

'My partner, Mr Pryde, owned the gun and was very proud of it. When he killed himself I knew that he meant me to have it. That was why he cut his wrists instead of shooting himself, which would have been quicker and easier.'

The coroner looked up sharply.

'And were you there when he killed himself?'

'No, sir. But I found the body.'

There was a murmur of sympathy from the court; she could feel their concern.

'Did you know that the gun wasn't licensed?'

'No, sir, but I think I suspected that it might not have been. I brought it with me on this case because I didn't want to leave it in the office and because I found it a comfort. I meant to check up on the licence as soon as I got back. I didn't expect ever to use the gun. I didn't really think of it as a lethal weapon. It's just that this was my first case and Bernie had left it to me and I felt happier having it with me.'

'I see,' said the coroner.

Cordelia thought that he probably did see and so did the court. They were having no difficulty in believing her because she was telling the somewhat improbable truth. Now that she was about to lie, they would go on believing her.

'And now will you please tell the court how Sir Ronald came to take the gun from you?'

'It was on my first visit to Garforth House when Sir Ronald was showing me his son's bedroom. He knew that I was the sole owner of the Agency, and he asked me if it wasn't a difficult and rather frightening job for a woman. I said that I wasn't frightened but that I had Bernie's gun. When he found that I had it with me in my bag he made me hand it over to him. He said that he didn't propose to engage someone who might be a danger to other people or herself. He said that he wouldn't take the responsibility. He took the gun and the ammunition.'

'And what did he do with the gun?'

Cordelia had thought this one out carefully. Obviously he hadn't carried it downstairs in his hand or Miss Learning would have seen it. She would have liked to have said that he put it into a drawer in Mark's room but she couldn't remember whether the bedside table had had any drawers. She said:

'He took it out of the room with him; he didn't tell me where. He was only away for a moment and then we went downstairs together.'

'And you didn't set eyes on the gun again until you saw it on the floor close to Sir Ronald's hand when you and Miss Learning found his body?'

'No, sir.'

Cordelia was the last witness. The verdict was quickly given, one that, the court obviously felt would have been agreeable to Sir Ronald's scrupulously exact and scientific brain. It was that the deceased had taken his own life but that there was no evidence as to the state of his mind. The coroner delivered at length the obligatory warning about the danger of guns. Guns, the court were informed, could kill people. He managed to convey that unlicensed guns were particularly prone to this danger. He pronounced no strictures on Cordelia personally although it was apparent that this restraint cost him an effort. He rose and the court rose with him.

After the coroner had left the bench the court broke up into little whispering groups. Miss Learning was quickly surrounded. Cordelia saw her shaking hands, receiving condolences, listening with grave assenting face to the first tentative proposals for a memorial service. Cordelia wondered how she could ever have feared that Miss Learning would be suspected. She herself stood a little apart, delinquent. She knew that the police would charge her with illegal possession of the gun. They could do no less. True, she would be lightly punished, if punished at all. But for the rest of her life she would be the girl whose carelessness and naivete had lost England one of her foremost scientists.

As Hugo had said, all Cambridge suicides were brilliant. But about this one there could be little doubt. Sir Ronald's death would probably raise him to the status of genius.

Almost unnoticed, she came alone out of the courtroom on to Market Hill. Hugo must have been waiting; now he fell into step with her.

'How did it go? I must say death seems to follow you around, doesn't it?'

'It went all right. I seem to follow death.' 'I suppose he did shoot himself?' 'Yes. He shot himself.' 'And with your gun?'

'As you will know if you were in court. I didn't see you.'

'I wasn't there, I had a tutorial, but the news did get around. I shouldn't let it worry you. Ronald Callender wasn't as important as some people in Cambridge may choose to believe.'

'You know nothing about him. He was a human being and he's dead. The fact is always important.'

'It isn't, you know, Cordelia. Death is the least important thing about us. Comfort yourself with Joseph Hall. "Death borders upon our birth and our cradle stands in the grave." And he did choose his own weapon, his own time. He'd had enough of himself. Plenty of people had had enough of him.'

They walked together down St Edward's Passage towards King's Parade. Cordelia wasn't sure where they were making for. Her need at present was just to walk, but she didn't find her companion disagreeable.

She asked:

'Where's Isabelle?'

'Isabelle is home in Lyons. Papa turned up unexpectedly yesterday and found that mademoiselle wasn't exactly earning her wages. Papa decided that dear Isabelle was getting less – or it may have been more – out of her Cambridge education than he had expected. I don't think you need worry about her. Isabelle is safe enough now. Even if the police do decide that it's worthwhile going to France to question her – and why on earth should they? – it won't help them. Papa will surround her with a barrage of lawyers. He's not in a mood to stand any nonsense from Englishmen at present.'

'And what about you? If anyone asks you how Mark died, you'll never tell them the truth?'

'What do you think? Sophie, Davie and I are safe enough. I'm reliable when it comes to essentials.'

For a moment Cordelia wished that he were reliable in less essential matters. She asked:

'Are you sorry about Isabelle leaving?'

'I am rather. Beauty is intellectually confusing; it sabotages common sense. I could never quite accept that Isabelle was what she is: a generous, indolent, over-affectionate and stupid young woman. I thought that any woman as beautiful as she must have an instinct about life, access to some secret wisdom which is beyond cleverness. Every time she opened that delicious mouth I was expecting her to illumine life. I think I could have spent all my life just looking at her and waiting for the oracle. And all she could talk about was clothes.'

'Poor Hugo.'

'Never poor Hugo. I'm not unhappy. The secret of contentment is never to allow yourself to want anything which reason tells you you haven't a chance of getting.'

Cordelia thought that he was young, well off, clever, even if not clever enough, handsome; there wasn't much that he would have to forgo on that or any other criteria.
