These were not highly comforting reflections, but there was still another and a better in reserve. What if, after all, the man were himself a felon? Might he not be a companion crib-cracker? In that case they would merely have to divide the spoils.
"Hey, in dere," cried Pierre, suddenly struck with an idea. "What is de combination hof de safe?"
"Fifteen—three—seventy-three!" came back in sepulchral tones.
It was evidently growing harder and harder to draw breath through the tiny aperture.
Thus it transpired that at the expiration of fifteen seconds the lock of the vault gave back the same resonant click it had rendered eight minutes previously. Thanks to the timely advent of Pierre and Baptiste it opened as lightly, as airily, and as decisively as airily, and as decisively as it had closed 480 seconds before on the unhappy accountant.
The head book-keeper gasped once or twice, but without any assistance stepped out into the free air. He was very pale and his dress was much rent and disordered when his feet touched the floor. But this pallor quickly made way for a red flush at perceiving the two burglars, with the implements of their profession strewn around them.
Meanwhile Pierre and Baptiste themselves stood transfixed by the sheer novelty of the situation.
Without any kind of speech or warning, or without making any attempt at bravado, the book-keeper walked deliberately to his desk and rang an electric call for the police. Simultaneously it seemed, for so rapid and quiet was the action, he opened a drawer, took out a small revolver, and covered both burglars with a fatal precision. As he did so he uttered these remarkable words:—
"Gentlemen, I would, indeed, be the basest of men if I did not feel profoundly grateful for the service you have just rendered me. I shall always regard you as any right-minded man should regard those who have saved his life with imminent peril to themselves or, which is just the same, to their liberty. Any demand in reason you make of me I shall make an effort to perform—but my duty to my employers I regard as paramount. I have accumulated a little money, and with it I propose to engage the best counsel in your defence, which is certainly marked by mitigating circumstances. If, on the other hand, you are convicted———"
Here the officers of justice entered, having broken open the door with a crash.
