He had an old professional's exact sense of passing time, and he knew that a full minute had already gone by since the explosion.

No one could be dead yet, even in that press, but there were few seconds to spare, fewer and fewer.
Then another sound was heard, a very pure strong note, high above his own tones, a beautiful round note, that made one think of gold and silver bells, and that filled the house instantly, like light, and reached every ear, even through the terror that was driving the crowd mad in the dark.
A moment more, an instant's pause, and Cordova had begun Lucia's song again at the beginning, and her marvellous trills and staccato notes, and trills again, trills upon trills without end, filled the vast darkness and stopped those four thousand men and women, spellbound and silent, and ashamed too.
It was not great music, surely; but it was sung by the greatest living singer, singing alone in the dark, as calmly and as perfectly as if all the orchestra had been with her, singing as no one can who feels the least tremor of fear; and the awful tension of the dark throng relaxed, and the breath that came was a great sigh of relief, for it was not possible to be frightened when a fearless woman was singing so marvellously.
Then, still in the dark, some of the musicians struck in and supported her, and others followed, till the whole body of harmony was complete; and just as she was at the wildest trills, at the very passage during which the crash had come, the lights went up all at once; and there stood Cordova in white and lace, with her eyes half shut and shaking her outstretched hands as she always made them shake in the mad scene; and the stage was just as it had been before the accident, except that Schreiermeyer was standing near the singer in evening dress with a perfectly new and shiny high hat on the back of his head, and his mouth wide open.
The people were half hysterical from the past danger, and when they saw, and realised, they did not wait for the end of the air, but sent up such a shout of applause as had never been heard in the Opera before and may not be heard there again.
Instinctively the Primadonna sang the last bars, though no one heard her in the din, unless it was Schreiermeyer, who stood near her.

When she had finished at last he ran up to her and threw both his arms round her in a paroxysm of gratitude, regardless of her powder and chalk, which came off upon his coat and yellow beard in patches of white as he kissed her on both cheeks, calling her by every endearing name that occurred to his polyglot memory, from Sweetheart in English to Little Cabbage in French, till Cordova laughed and pushed him away, and made a tremendous courtesy to the audience.
Just then a man in a blue jacket and gilt buttons entered from the left of the stage and whispered a few words into Schreiermeyer's ear.
The manager looked grave at once, nodded and came forward to the prompter's box.

The man had brought news of the accident, he said; a quantity of dynamite which was to have been used in subterranean blasting had exploded and had done great damage, no one yet knew how great.

It was probable that many persons had been killed.
But for this news, Cordova would have had one of those ovations which rarely fall to the lot of any but famous singers, for there was not a man or woman in the theatre who had not felt that she had averted a catastrophe and saved scores of lives.
