But to the inquest she would not go.

She could not sit there with all her load of knowledge and not at some point be tempted to stand up and tell the truth and have the responsibility off her soul.

Who knew what rat the police might smell out? They had come and viewed the gymnasium, and measured things, and reckoned the weight of the boom, and interviewed all and sundry, and consulted the various experts on the subject, and listened and said nothing. They had taken away the pin that had been so fatally insecure; and that may have been mere routine, but who could tell? Who could tell what suspicions they might be entertaining in their large calm breasts and behind their polite expressionless faces?

But as it turned out, a quite unexpected saviour appeared at the inquest. A saviour in the person of Arthur Middleham, tea importer, of 59 West Larborough Road; that is to say, a resident in one of the villas which lined the highroad between West Larborough and the gates of Leys. Mr Middleham knew nothing about College except that it was there, and that the scantily attired young women who flew about the district on bicycles belonged to it. But he had heard about the accident. And it had struck him as odd that a pin in the gymnasium at Leys had moved out of place on the same morning, and presumably about the same time, as a pane of glass had been shaken out of his drawing-room window by a passing convoy of tanks from the works at South Larborough. His theory was, in fact, the same as Miss Lux's; vibration. Only Miss Lux's had been a hit in the dark and of no value. Mr Middleham's was reasonable and backed by three-dimensional evidence: a pane of broken glass.

And as always when someone has given a lead, there were gratuitous followers. (If someone invented a story and wrote to the Press that they had seen a green lion in the sky at 5.30 the previous evening, at least six people would have seen it retrospectively.) An excited woman, hearing Mr Middleham's evidence, got up from the body of the hall and said that her ginger jar that she had had for years had dropped off the little table in her window of its own accord at the same time.

"Where do you live, madam?" the coroner asked, when he had winkled her out of the crowd and installed her as evidence.

She lived in the cottages between Leys and Bidlington, she said. On the highroad? Oh, yes, much too much on the highroad; in the summer the dust was a fair sickener, and when the traffic was them there tanks — . No, she had no cat. No, there had been no one in the room. She had just come in after breakfast and found it on the floor. It had never happened before.

Poor O'Donnell, very nervous but clear and decided, gave evidence that she had put up the end by the wall and that Rouse had attended to the middle end. "Putting it up" meant hoisting the boom by the pulley rope and pushing the pin under it to keep it up. It was also kept up, to a certain extent, by the rope, the hanging end of which was given a turn round a cleat on the upright. No, they had not tested the apparatus before going.

Froken, asked about the rope which had not proved a substitute for the pin, said that it had not been wound tightly enough to prevent sagging when the pin was removed. The twisting of the rope round the cleat was an automatic gesture, and no student thought of it as a precautionary measure. It was that, in fact, of course. The metal of the pin might break through some fault, and the rope in that case took the strain. Yes, it was possible that a rope, unaccustomed to a greater strain than the weight of a boom, stretched under the sudden addition of a ten-stone burden, but she thought not. Gymnasium ropes were highly tested and guaranteed. It was much more likely that the twist Miss Rouse gave it had been inadequate.

And that seemed to be all. It was an unfortunate accident. The pin the police had abstracted had been used by all and sundry during the Demonstration, and was no evidence of anything.
