In sympathetic accents he asked: “Is it a fact that your father was suffering from cancer in a painful form?”
“It was beginning to grow very painful,” said Ruth sadly.
“Did he make a will and put all his affairs in order a few days before he died?”
“Three days,” said Ruth.
“Did he ever express an intention of committing suicide?”
“He said that he would stick it out for a little while and then end it all,” said Ruth. She paused and added: “And that is what he did do.”
One might almost say that the Court started. I think that everyone in it moved a little, so that there was a kind of rustling murmur. Garbould threw himself back in his seat with a snort of incredulity and glowered at Ruth.
“Will you tell the Court your reasons for that statement?” said Hazeldean.
Ruth seemed to pull herself together; the flush had faded from her face and she was looking very tired; then she began in a quiet, even voice: “I never believed for a moment that Mr. Willoughton murdered my father. If my father had murdered Mr. Willoughton it would have been a different matter.”
Garbould leaned forward and snarled that it was not her beliefs or fancies that were wanted, but facts.
I did not think that she heard him; she was concentrating on giving her reasons exactly; she went on in the same quiet tone: “Of course, like everybody else I puzzled over the weapon: what it was and where it had got to. I did not believe that it was a pointed piece of a half-inch steel rod. If anybody had come to the Turkish bath meaning to murder my father and hide the weapon, they wouldn’t have used one so big and so difficult to hide, when a hat-pin would have done just as well and could be hidden much more easily. But what puzzled me most was the tea-leaf in the wound. All the other tea-leaves that came out of the flask were lying on the floor. Inspector Brackett told me they were. And I couldn’t believe that one tea-leaf had fallen on to my father at the very place above his heart at which the point of the weapon had penetrated the skin and got driven in by it. It was too much of a coincidence for me to swallow. But I got no nearer understanding it than anyone else.”
Garbould broke in in a tone of some exasperation and told her to come to the facts. Hazeldean rose and protested that the witness should not be interrupted; that she had solved a mystery which had puzzled some of the best brains in England, and she should be allowed to tell her story in her own way.
Again Ruth did not appear to listen to them, and when they stopped she went on in the same quiet voice: “Of course I remembered that Dad had talked to putting an end to it; but no one with a wound like that could get up and hide the weapon. Then, the night before last I dreamt that I went into the laboratory and saw a piece of steel rod, pointed, lying on the table at which my father used to work.”
“Dreams now!” murmured Garbould contemptuously; and he leaned back and folded his hands over his stomach.
“I didn’t think much of the dream, of course,” Ruth went on. “I had been puzzling about it all so hard for so long that it was only natural to dream about it. But after breakfast I had a sudden feeling that the secret was in the laboratory if I could only find it. I did not attach any importance to the feeling; but it went on growing stronger; and after lunch I went to the laboratory and began to hunt.
“I looked through all the drawers and could find nothing. Then I went round the room looking at everything and into everything, instruments and retorts and tubes and so on. Then I went into the middle of the floor and looked slowly round the room pretty hard. Against the wall, near the door, lying ready to be taken away, was a gas cylinder rolled it over to see what gas had been in it and it had no label on it.”
She paused to look round the Court as if claiming its best attention; then she went on: “Now that was very queer because every gas cylinder must have a label on it – so many gases are dangerous. I turned on the cylinder and nothing came out of it. It was quite empty. Then I went to the book in which all the things which come in are entered, and found that ten days before Dad died he had had in a cylinder of CO2 and seven pounds of ice. Also he had had seven pounds of ice every day till the day of his death. It was the ice and the CO2 together that gave me the idea. CO2, carbon dioxide, has a very low freezing-point – eighty degrees centigrade – and as it comes out of the cylinder and mixes with the air it turns into very fine snow; and that snow, if you compress it, makes the hardest and toughest ice possible. It flashed on me that Dad could have collected this snow and forced it into a mould and made a weapon that would not only inflict that wound but would disappear instantly!”
She paused again to look round the Court at about as rapt a lot of faces as any narrator could desire. Then she went on: “I knew that that was what he had done. I knew it for certain. Carbon dioxide ice would make a hard, tough dagger, and it would melt quickly in the hottest room of a Turkish bath and leave no smell because it is scentless. So there wouldn’t be any weapon. And it explained the tea-leaf too. Dad had made a carbon dioxide dagger perhaps a week before he used it, perhaps only a day. And he had put it into the thermos flask as soon as he had made it. The thermos flask keeps out the heat as well as the cold, you know. But to make sure that it couldn’t melt at all he kept the flask in ice till he was ready to use the dagger. It’s the only way you can explain that tea-leaf. It came out of the flask sticking to the point of the dagger and was driven into the wound!”
She paused again and one might almost say that the Court heaved a deep sigh of relief.
Then Garbould asked in an unpleasant and incredulous voice: “Why didn’t you take this fantastic theory straight to the police?”
“But that wouldn’t have been any good,” she protested quickly. “It was no use my knowing it myself; I had to make other people believe it; I had to find evidence. I began to hunt for it. I felt in my bones that there was some. What I wanted was the mould. I found it!”
She uttered the words in a tone of triumph and smiled at Willoughton; then she went on: “At least I found bits of it. In the box into which we used to throw odds and ends, scraps of material, damaged instruments, and broken test tubes, I found some pieces of vulcanite; and I saw at once that they were bits of a vulcanite container. I took some wax and rolled it into a rod about the right size and then I pieced the container together on the outside of it – at least most of it – there are some small pieces missing. It took me nearly all night. But I found the most important bit – the pointed end!”
She dipped her hand into her handbag and drew out a black object about nine inches long and three quarters of an inch thick and held it up for every one to see.
Someone, without thinking, began to clap; and there came a storm of applause that drowned the voice of the Clerk calling for order and the bellowing of Garbould.
When the applause died down, Hazeldean, who never misses the right moment, said: “I have no more questions to ask the witness, my lord,” and sat down.
That action seemed to clinch it in my eyes, and I have no doubt, it clinched it in the eyes of the jury.
The purple Garbould leant forward and almost bellowed at Ruth: “Do you expect the jury to believe that a well-known man like your father died in the act of deliberately setting a dastardly trap to hang the prisoner?”
Ruth looked at him, shrugged her shoulders, and said with a calm acceptance of the facts of human nature one would expect to find only in a much older woman: “Oh, well, Daddy was like that. And he certainly believed he had very good reasons for killing Mr. Willoughton.”
