'But did not Gragnon destroy it?' Marc inquired.

'It seems not. Having shown it to the jurors he did not dare to do so, but simply placed it with the papers in the case, among which it must still be. At least, such is the conviction of Delbos, based on certain information he has obtained. Thus the question is to exhume it from among the records, and it is not easy to devise a plausible motive for doing so.... Nevertheless, we are making progress.' And after a pause David added: 'And you, my friend, have you any good news?'

'Yes, good and great news.'

Then Marc slowly recounted all that had happened: Sébastien's illness, Madame Alexandre's despair, followed by her remorse and terror, which had prompted her to hand him the long-sought duplicate of the copy-slip, on which duplicate one found both the stamp of the Brothers' school and a paraph which undoubtedly represented Brother Gorgias's initials. 'Here it is,' said Marc. 'There, you see, is the stamp, in the very corner which was torn away from the copy found near little Zéphirin's body. We fancied that it might have been bitten off by the victim, but Father Philibin at least had time to tear it off; on that point the recollections of Mignot, my assistant, are precise.... Now, look at the paraph. It is identical with the other which figured at the trial, but it is more legible, and one can fully distinguish Brother Gorgias's initials,[1] that is an F and a G interlaced, which the experts, Masters Badoche and Trabut, with extraordinary aberration, persisted in declaring to be an L and an S, otherwise your brother's initials.... My conviction is now absolute: the culprit is Brother Gorgias, and none other.'

[1] Brother Gorgias = Frère Gorgias.

With passionate eagerness they all stared at the narrow yellow strip of paper produced by Marc, and scrutinised it in the pale lamplight. The old Lehmanns quitted their sewing and thrust their faces forward as if reviving to life. Rachel had emerged from her torpor, and stood there quivering, while the two children, Joseph and Sarah, their eyes aflame, pushed one another in order that they might see the better. Finally David, amid the deep silence of that mourning home, took the paper from Marc and examined it.

'Yes, yes,' he said, 'my conviction is the same as yours. What was suspected has now become certain. Brother Gorgias is the guilty man!'

A long discussion followed; all the facts were recalled in succession, and united in one sheaf. They threw light on each other, and all tended to the same conclusion. Apart from the material proofs which were beginning to come in, there was a moral certainty, the demonstration as it were of a mathematical problem, which reasoning sufficed to solve. No doubt obscurity still hung around a few points, such as the presence of the copy-slip in the Brother's pocket, and the fate of the corner on which the stamp had been impressed. But all the rest seemed certain: Gorgias returning home on the night of the crime, chance bringing him before Zéphirin's open and lighted window, temptation, and afterwards murder; then, on the morrow, chance likewise bringing Father Philibin and Brother Fulgence on the scene in such wise that they became mixed up in the tragedy and were forced to act in order to save one of their fellows. And how plainly did the mutilation of the copy-slip designate the culprit, whose name was virtually proclaimed also by the fierce campaign which had ensued, the great efforts which the Church had made in order to shield him, and cause an innocent man to be sentenced in his stead. Moreover, each day now brought fresh light, and before long the whole huge edifice of falsehood would crumble.

'So that is the end of our wretchedness!' exclaimed old Lehmann, becoming quite gay. 'It will only be necessary to show that paper and Simon will be restored to us.'

The two children were already dancing with delight, repeating in blissful accents: 'Oh! papa will come back! papa will come back!'
