“There come two creatures,” muttered Gavroche.

The first form seemed to be some elderly bourgeois, who was bent and thoughtful, dressed more than plainly, and who was walking slowly because of his age, and strolling about in the open evening air.

The second was straight, firm, slender. It regulated its pace by that of the first; but in the voluntary slowness of its gait, suppleness and agility were discernible. This figure had also something fierce and disquieting about it, the whole shape was that of what was then called an elegant; the hat was of good shape, the coat black, well cut, probably of fine cloth, and well fitted in at the waist. The head was held erect with a sort of robust grace, and beneath the hat the pale profile of a young man could be made out in the dim light. The profile had a rose in its mouth. This second form was well known to Gavroche; it was Montparnasse.

He could have told nothing about the other, except that he was a respectable old man.

Gavroche immediately began to take observations.

One of these two pedestrians evidently had a project connected with the other. Gavroche was well placed to watch the course of events. The bedroom had turned into a hiding-place at a very opportune moment.

Montparnasse on the hunt at such an hour, in such a place, betokened something threatening. Gavroche felt his gamin’s heart moved with compassion for the old man.

What was he to do? Interfere? One weakness coming to the aid of another! It would be merely a laughing matter for Montparnasse. Gavroche did not shut his eyes to the fact that the old man, in the first place, and the child in the second, would make but two mouthfuls for that redoubtable ruffian eighteen years of age.

While Gavroche was deliberating, the attack took place, abruptly and hideously. The attack of the tiger on the wild ass, the attack of the spider on the fly. Montparnasse suddenly tossed away his rose, bounded upon the old man, seized him by the collar, grasped and clung to him, and Gavroche with difficulty restrained a scream. A moment later one of these men was underneath the other, groaning, struggling, with a knee of marble upon his breast. Only, it was not just what Gavroche had expected. The one who lay on the earth was Montparnasse; the one who was on top was the old man. All this took place a few paces distant from Gavroche.

The old man had received the shock, had returned it, and that in such a terrible fashion, that in a twinkling, the assailant and the assailed had exchanged rôles.
