The coroner sat in a stuffy little room, the windows of which were open. Nevertheless, with the place crowded the atmosphere was oppressively hot. The inquiry was long and tedious, for after evidence had been given as to the lieutenant’s departure, and eyewitnesses had described his fall, there came a quantity of highly technical evidence put forward by the Admiralty with the object of proving that the machine had been in a perfectly satisfactory condition. The Gnome engine was of 80 horse-power, the monoplane had been thoroughly overhauled only four days previously, and the flights which Barclay had made in her from Eastchurch proved that there had been no defect which could have been detected.
Curious it was that that inquiry was being held in the same hotel where Ralph Ansell and Jean Libert had taken their tea.
One man alone knew the terrible truth—the man who, on that fatal evening, had crept under the hedge unseen, and substituted the small steel bolt with one of wood with such an expert, unerring hand—the man who had stood up in the cab and calmly watched the awful result of his evil handiwork without the slightest sign of pity or remorse.
He had hurled Noel Barclay to his death with as little compunction as he would have crushed a fly. And yet little Jean, with the neat figure and great, dark eyes, in her innocence and ignorance, loved him so dearly and so well. She never dreamed the truth, and therefore he was her ideal, while she was his affianced wife.
In that small, over-crowded room, clean-shaven experts stood up one after the other, each expressing a different theory as to the cause of the accident.
When poor Barclay had been found, the engine was lying upon his chest, his neck was broken, his face battered out of all recognition, and both arms were broken. So utterly wrecked was the machine that it presented the appearance of a mass of splintered wood, tangled wires, and torn strips of fabric flapping in the wind.
All had been examined carefully, piece by piece, after the mangled remains of the unfortunate pilot had been extricated. The bolt was missing and search failed to find it. A quantity of evidence was forthcoming, and many theories advanced, the conclusion arrived at being that the left wing collapsed owing to undue strain, and the machine, instantly out of control, fell to earth.
There was but one verdict which the twelve honest men of Mundesley could return.
Expert evidence agreed that the quick-release at the end of one of the stay-wires was faulty. The steel bolt holding the main-stay cable and secured by a split-pin could not be found. It had evidently broken and fallen out, so that the left wing, being thus unsupported, had collapsed in mid-air.
