“But the cigarette holder shoved in the nozzle of the gas-tube to form a mouthpiece!” he exclaimed. “That seemed to me so ingenious!”
“Yes, so it was,” Mrs. Bradley regretfully conceded. “But it happened to be my ingenuity, not Miss Bonnet’s at all. You see, she never used a cigarette holder. On the other hand, Ulrica Doyle, quite suddenly, began helping her cousin Ursula with her Latin and her Science. That seemed to me significant.”
“Ulrica?”
“Yes. Carbon monoxide is easy enough to make, and Ulrica used to take those mysterious walks, which the Community, believing them harmless, did not supervise.”
“You mean children ought to be under constant supervision? I thought you were such an apostle of liberty!”
“I am, dear child, I hope. And it is now part of an inevitable reaction, that Ulrica knows she betrayed the kindness of Mother Francis and the Reverend Mother Superior.”
“But I thought you had fixed on Miss Bonnet!”
“Miss Bonnet,” said Mrs. Bradley, “is almost a halfwit in some respects, but even she could hardly have missed the conclusion that, if a child was going to be murdered, the time to do it was while the nuns were all in church between two o’clock and half-past. Even if nothing else had indicated that Miss Bonnet was not the culprit, I should have given up thinking her guilty when I heard about that half-hour’s special coaching she gave to the private-school girls.”
“But she knocked out that orphan child deliberately during the netball practice, you thought.”
“Yes, I know she did. She needed an excuse to get into the Orphanage, I think. When she had stolen the chalice and paten she wanted a hiding place very near at hand, from which she could take them when the search had ceased to be local and had widened.”
“But why pick the Orphanage?”
“Because nobody would suspect the poor orphans of stealing the chalice and paten, and suspicion would hardly be attached to Mother Ambrose and Mother Jude.”
“She just snooped round for a hiding-place?”
“Whilst Mother Ambrose and Mother Jude were busy. Yes, I think so.”
“But where was the child killed, mother?”
“In the bathroom where she was found. The carbon monoxide could have been made in several ways by a girl with some knowledge of chemistry—by burning some charcoal, for instance. The problem of how the child got into the guest-house bothered me for a time, but I’m quite sure now that Ulrica told her Miss Bonnet was there and wanted to see her about that extra coaching in physical training. You remember that that was one of the reasons brought forward in favour of the suicide verdict?—that the child was in trouble at school? Well, she was in trouble—if you can call it that!— with Miss Bonnet, and had been told she must have some extra practice.”
“But the bathroom?”
“Oh, we can imagine, I think, what happened. First they looked in at the parlour. ‘She isn’t here. She said she might be upstairs, and we were to find her.’ You know what children are, and Ursula would have believed every word from her cousin, the cousin who was helping her with her work, helping her to gain merit badges from her teachers, helping to make her so happy. You remember that many of the nuns decided that so happy a child would not have killed herself? Then, when they got to the bathroom door, the whiff of the carbon monoxide—‘look what I’m going to show Mother Saint Simon to-morrow.’ The fatal sniff, the climb out of the window to release the rest of the gas where it might harm no one, the horrifying discovery that the child was not merely unconscious, but was dead, the panic-stricken tearing off of the clothes, the water rising higher and higher in the bath, the closed window—to conceal, if possible, even from herself, that she had been out on the roof to get rid of the dangerous evidence—and then, the flight to the church, quite the most characteristic touch. Mind you, I think this: that if all had gone exactly according to plan, and the child had been found, not gassed in the bath, but drowned, and a verdict of Accidental Death had been returned, even Ulrica herself would have forgotten, very soon, that the death was due to her agency. Unfortunately for her, suicide is a dreadful sin from the point of view of the Church. That point of view she accepted, and immediately it worried and confused her. To have her innocent cousin—for she never thought of her except as a cypher and a pawn— accused of mortal sin, and wrongly accused, worked on her mind, and roused in her a dormant suicide complex.”
“But what are you going to do about it now?”
“Nothing, dear child. Why should I? Reverend Mother Superior, Mother Saint Francis, and old Mother Gregory, the Sacristan, were all convinced of her guilt.”
“But she can’t get off scot free!”
“Scot free?” said Mrs. Bradley. She laughed—not her usual cackle, but a harsh sound, sardonic and pitiful. “Why do you think I have had her so carefully watched? The nuns knew, if you do not. That abortive attempt at suicide in the car was her first, although the nuns tell me that after the death she frequently walked in her sleep and always towards an open window or towards the head of the stairs. The tendency to suicide was innate, and it was that which made the murder possible. To a Christian, Catholic or Protestant, murder and suicide should be, alike, impossible. Logically, a belief in the resurrection of the dead must always neutralise any belief in death as a solution of human problems. Murder, including self-murder, is evidence of an innate non-Christian belief that death ends all, and this child’s father, remember, an atheist, was a renegade Catholic churchman. The child, brought up without positive religious beliefs, was always in a state of mental conflict, for she could never reconcile her early training with her later religious ecstasies. All adolescents are at war within themselves, but in this child the fight was terrible enough to overwhelm her. Somehow, she had to rehabilitate herself in the eyes of God. Somehow, the family fortune had got to go to the Church. That was how she saw it. She had to expiate, somehow, the terrible sin of her father’s atheism. It had become a burden too terrible to be borne, and true reason broke beneath the strain of it.”
“But, mother, she must have been mad.”
“On the contrary, perfectly sane. Her tragedy was that she had a single-track mind, as the vulgar have it. If that mind held two very powerful basic ideas, it followed that those ideas must be in conflict.”
“But you can’t just leave it like this!”
“She will never commit another crime.”
“But, mother, you’ll have to expose her! The murder was such a wanton, wicked thing. It was something planned for weeks, carefully, painstakingly, devilishly; every circumstance taken into account and used to the best advantage. It was only through the merest accident that it failed to hoodwink everybody! After all, you needn’t worry! They wouldn’t hang the girl!”
“No, they wouldn’t, would they?” said Mrs. Bradley. Walking without her customary briskness, she led the way to the guest-house.
“You had a good deal of evidence against Miss Bonnet, though, hadn’t you?” her son observed tentatively, as they passed the wicket gate. “The towel, the absence of the bath-sheet, the fact that she lied about her visit to Kelsorrow School—or, rather, about the time she went there—the fact that she made two or three attempts to ‘out’ you when she found you were getting rather warm—that jar of bath salts, for instance! Nobody here but Miss Bonnet could have shinned over that high brick wall, and so got back undetected to the school.”
“The evidence was nearly all circumstantial, dear child. And Miss Bonnet would never have murdered the girl in the guest-house. For her it would have been risky in the extreme. She would have wrung the child’s neck and thrown the body into one of the fissures of the cliff or into a pool on the moor. Miss Bonnet’s reactions are lively, violent, and bear all the colourful stigmata of a shallow and rather weak nature. Besides, I don’t think at first it occurred to Miss Bonnet that the children could be a menace. Even if they had gone to New York and recognised the chalice and paten in Timothy Doyle’s collection, she thought he would tell them that the convent had sold him the copies. Nobody but an expert could tell them from the originals, you see.”
