‘How horrible,’ said Jane Helier with a shudder. ‘It’s like—it’s like fattening on your victim’s blood.’
‘And yet, in another way, I may be doing her an injustice,’ went on Dr Lloyd. ‘She certainly said something before she left, which pointed in an entirely different direction. There may be, I think there are, consciences which work very slowly—which take some time to awaken to the enormity of the deed committed.
‘It was the evening before her departure from the Canaries. She had asked me to go and see her, and had thanked me very warmly for all I had done to help her. I, of course, made light of the matter, said I had only done what was natural under the circumstances, and so on. There was a pause after that, and then she suddenly asked me a question.
‘ “Do you think,” she asked, “that one is ever justified in taking the law into one’s own hands?”
‘I replied that that was rather a difficult question, but that on the whole, I thought not. The law was the law, and we had to abide by it.
‘ “Even when it is powerless?”
‘ “I don’t quite understand.”
‘ “It’s difficult to explain; but one might do something that is considered definitely wrong—that is considered a crime, even, for a good and sufficient reason.”
‘I replied drily that possibly several criminals had thought that in their time, and she shrank back.
‘ “But that’s horrible,” she murmured. “Horrible.”
‘And then with a change of tone she asked me to give her something to make her sleep. She had not been able to sleep properly since—she hesitated—since that terrible shock.
‘ “You’re sure it is that? There is nothing worrying you? Nothing on your mind?”
‘ “On my mind? What should be on my mind?”
‘She spoke fiercely and suspiciously.
‘ “Worry is a cause of sleeplessness sometimes,” I said lightly.
‘She seemed to brood for a moment.
‘ “Do you mean worrying over the future, or worrying over the past, which can’t be altered?”
‘ “Either.”
‘ “Only it wouldn’t be any good worrying over the past. You couldn’t bring back—Oh! what’s the use! One mustn’t think. One must not think.”
‘I prescribed her a mild sleeping draught and made my adieu. As I went away I wondered not a little over the words she had spoken. “You couldn’t bring back—” What? Or who?
‘I think that last interview prepared me in a way for what was to come. I didn’t expect it, of course, but when it happened, I wasn’t surprised. Because, you see, Mary Barton struck me all along as a conscientious woman—not a weak sinner, but a woman with convictions, who would act up to them, and who would not relent as long as she still believed in them. I fancied that in the last conversation we had she was beginning to doubt her own convictions. I know her words suggested to me that she was feeling the first faint beginnings of that terrible soul-searcher—remorse.
‘The thing happened in Cornwall, in a small watering-place, rather deserted at that season of the year. It must have been—let me see—late March. I read about it in the papers. A lady had been staying at a small hotel there—a Miss Barton. She had been very odd and peculiar in her manner. That had been noticed by all. At night she would walk up and down her room, muttering to herself, and not allowing the people on either side of her to sleep. She had called on the vicar one day and had told him that she had a communication of the gravest importance to make to him. She had, she said, committed a crime. Then, instead of proceeding, she had stood up abruptly and said she would call another day. The vicar put her down as being slightly mental, and did not take her self-accusation seriously.
‘The very next morning she was found to be missing from her room. A note was left addressed to the coroner. It ran as follows:
‘I tried to speak to the vicar yesterday, to confess all, but was not allowed. She would not let me. I can make amends only one way—a life for a life; and my life must go the same way as hers did. I, too, must drown in the deep sea. I believed I was justified. I see now that that was not so. If I desire Amy’s forgiveness I must go to her. Let no one be blamed for my death—Mary Barton.
‘Her clothes were found lying on the beach in a secluded cove nearby, and it seemed clear that she had undressed there and swum resolutely out to sea where the current was known to be dangerous, sweeping one down the coast.
‘The body was not recovered, but after a time leave was given to presume death. She was a rich woman, her estate being proved at a hundred thousand pounds. Since she died intestate it all went to her next of kin—a family of cousins in Australia. The papers made discreet references to the tragedy in the Canary Islands, putting forward the theory that the de
ath of Miss Durrant had unhinged her friend’s brain. At the inquest the usual verdict of Suicide whilst temporarily insane was returned.
‘And so the curtain falls on the tragedy of Amy Durrant and Mary Barton.’
There was a long pause and then Jane Helier gave a great gasp.
‘Oh, but you mustn’t stop there—just at the most interesting part. Go on.’
‘But you see, Miss Helier, this isn’t a serial story. This is real life; and real life stops just where it chooses.’
‘But I don’t want it to,’ said Jane. ‘I want to know.’
‘This is where we use our brains, Miss Helier,’ explained Sir Henry. ‘Why did Mary Barton kill her companion? That’s the problem Dr Lloyd has set us.’
‘Oh, well,’ said Miss Helier, ‘she might have killed her for lots of reasons. I mean—oh, I don’t know. She might have got on her nerves, or else she got jealous, although Dr Lloyd doesn’t mention any men, but still on the boat out—well, you know what everyone says about boats and sea voyages.’
Miss Helier paused, slightly out of breath, and it was borne in upon her audience that the outside of Jane’s charming head was distinctly superior to the inside.
‘I would like to have a lot of guesses,’ said Mrs Bantry. ‘But I suppose I must confine myself to one. Well, I think that Miss Barton’s father made all his money out of ruining Amy Durrant’s father, so Amy determined to have her revenge. Oh, no, that’s the wrong way round. How tiresome! Why does the rich employer kill the humble companion? I’ve got it. Miss Barton had a young brother who shot himself for love of Amy Durrant. Miss Barton waits her time. Amy comes down in the world. Miss B. engages her as companion and takes her to the Canaries and accomplishes her revenge. How’s that?’
‘Excellent,’ said Sir Henry. ‘Only we don’t know that Miss Barton ever had a young brother.’
‘We deduce that,’ said Mrs Bantry. ‘Unless she had a young brother there’s no motive. So she must have had a young brother. Do you see, Watson?’
‘That’s all very fine, Dolly,’ said her husband. ‘But it’s only a guess.’
