Frank laughed.
‘It’s an ingenious and fascinating tale, but of course it would be impossible to prove any of it. And even your ingenuity would be strained to find a reason for the murder of Mrs Graham!’
She shook her head.
‘It was not, of course, premeditated. Of the three, or perhaps we may say four, suspects, there are only two against whom there is any evidence. In the case of Mr Carey there is Mrs Traill’s statement that she heard Mrs Graham call out “How dare you, Nicholas Carey!” at a time which must have been very close to that of the murder, and when according to his own account he would have been at some considerable distance. This is evidence that Mrs Graham returned to the garden after her daughter had taken her in, and that she became aware of an intruder whom she took to be Nicholas Carey. It is no proof at all that it was Nicholas Carey. The second suspect is Mrs Harrison. As late as seven o’clock on Tuesday evening her diamond ring was undamaged. At ten o’clock on Wednesday morning one of the stones was missing. In the interval Mrs Graham had been murdered. Later the missing stone is found in a crack at the entrance to the gazebo and Mrs Harrison goes to extravagant lengths to provide herself with an alibi for Tuesday night. Mr Worple must come in for some suspicion, but there is nothing that really connects him with the crime, and in both his case and Mrs Harrison’s it is difficult to imagine what would take them to the gazebo at such an hour, unless of course they had an assignation there.’
He laughed.
‘A little far-fetched, don’t you think?’
‘Perhaps. And the motive for murder would be a weak one. But in Mr Blount’s case he could have had a quite compelling reason for silencing Mrs Graham. It is obvious that he had no opportunity of carrying out a really thorough test in the neighbourhood of the gazebo. When he came to view the house he doubtless went into the garden, but Miss Graham would certainly have accompanied him. I do not know to what extent a divining rod could be employed without its being plainly in evidence, but anyone who contemplated sinking a large sum of money in a project of this kind would certainly wish to make the strictest possible tests before committing himself.’
‘So Blount went to the gazebo to wave his divining rod and make sure of the gold?’
‘I will not go farther than to say that he might have gone there for such a purpose.’
‘And then?’
‘He knows that the household at The Lodge keeps early hours. What he could not know was that Mr Carey and Miss Graham would be meeting in the gazebo at half past ten, and that their meeting would be interrupted by Mrs Graham. Owing to this, she was awake at an hour when she should have been safely asleep. I think he must have used a torch – no doubt with great caution – and I think she must have seen it from the bathroom window. Certainly something took her up the garden again in a great hurry. She reaches the gazebo and calls out. You have to imagine the effect on the person whom she has surprised. He takes her by the throat, perhaps to stop her screaming. The rest follows.’
Frank nodded.
‘A good tale, and even a likely one! And not one single solitary shred of evidence to put before a jury! But in Carey’s case – well, I think it would be touch and go for him, depending on who was briefed for the defence and upon just what impression he made in the witness box.’
‘And if you were on such a jury, which way would your vote go?’
He laughed.
‘That would be telling!’
She said demurely,
‘I should very much like to be told.’
‘Very well, strictly between you and me I don’t think Carey did it. From what I have heard I should imagine she would have been an appalling mother-in-law, but I shouldn’t think he would go to the length of murdering her to avoid the relationship – too much awkwardness all round, and not enough incentive. He was marrying the girl anyhow, and as Mrs Graham had already found him in the gazebo once, it really didn’t matter whether she walked into him again.’
He received a look of intelligent commendation.
‘That is precisely the argument I should have put forward myself. But to return to the Blounts. I feel extremely anxious on her account. If he becomes seriously alarmed as to what she may have overheard, I fear for her safety. She is in just that vague shocked condition which would make it comparatively easy to stage an accident. She is, in fact, in a frame of mind conducive either to accident or suicide. And there would be no proof that it was not just a case of another neurotic woman laying down the burden which she feels no longer able to carry. Of course as long as she is here and in a guest house…’
He interrupted her.
‘They have left the guest house. I called in there on my way up, and they had gone. All very sudden and unpremeditated. Miss Madison was put out enough to want to blow off steam, and she told me all about it. It seems two of the guests were alarmed by Mr Blount calling out in his sleep last night. She said she just mentioned it to him when he came in in the early afternoon and he didn’t say anything then, but a little later he came down and said he had been called away in a hurry, upon which he telephoned for a taxi, paid the bill, and departed to catch the four-thirty. She seemed to think that he had taken offence.’
Miss Silver was looking exceedingly grave.
‘Did she say anything about Mrs Blount?’ He nodded.
‘She said she didn’t look as if she was fit to travel.’
THIRTY-EIGHT
THE BLOUNTS TRAVELLED by a slow train. It stopped at a great many stations, and every time it stopped people got in or got out. Sometimes the compartment was so crowded that Mrs Blount felt as if she couldn’t breathe. The morning had been cold, but the sun had come out and the afternoon was muggy. Most of the people who were travelling were far too warmly dressed, but nobody seemed to want to have a window open. The air became heavy with the smell of moth-ball and warm people and tobacco smoke. Mrs Blount shut her eyes, because when she tried to keep them open everything kept slipping out of focus. She couldn’t see how ill she looked – those pale eyelids closed and the dark marks like bruises underlining them. With her head tipped back and her colourless lips fallen apart, it really did seem as if those drooping lids might never rise again. Mr Blount in the opposite seat was stirred to anger. What did she want to go and make a show of herself like that for? Why couldn’t she behave like any of the other women in the compartment? There was one of them reading just the kind of rubbishy paper Millie was so fond of. Another was sucking peppermints, and a thin wiry woman in spectacles had got up quite a brisk argument with the person next to her. He leaned forward and touched Millie on the knee.
‘Here, you’d better not go to sleep, had you? You always say it gives you a headache if you sleep in the train.’
She started, looked at him nervously, and spoke in an undertone.
‘I just felt giddy.’
He began to wish he had left her alone. But perhaps it was all for the best. If anyone was going to remember seeing them, it would be recalled that her behaviour had been odd, and that he had been solicitous for her comfort. He said in his most agreeable voice,
‘Oh, well, you must do just what makes you most comfortable, my dear.’
She knew why he spoke to her like that. He was never sharp or angry with her in front of people. He had been the same with his first wife, the one who fell under a train. There had been some talk about that. He wasn’t there when it happened – or he wasn’t supposed to be there. And no one could say they had ever heard them quarrel. She shut her eyes again and tried not to think about Lucy Blount who had fallen under a train nearly four years ago.
