Scarcely had this smoke appeared, to vanish almost immediately, when all the innumerable crowd, knowing well that there was nothing else to wait for, and that all was said and done until ten o’clock the next morning, the time when the cardinals had their first voting, went off in a tumult of noisy joking, just as they would after the last rocket of a firework display; so that at the end of one minute nobody was there where a quarter of an hour before there had been an excited crowd, except a few curious laggards, who, living in the neighbourhood or on the very piazza itself; were less in a hurry than the rest to get back to their homes; again, little by little, these last groups insensibly diminished; for half-past nine had just struck, and at this hour the streets of Rome began already to be far from safe; then after these groups followed some solitary passer-by, hurrying his steps; one after another the doors were closed, one after another the windows were darkened; at last, when ten o’clock struck, with the single exception of one window in the Vatican where a lamp might be seen keeping obstinate vigil, all the houses, piazzas, and streets were plunged in the deepest obscurity. At this moment a man wrapped in a cloak stood up like a ghost against one of the columns of the uncompleted basilica, and gliding slowly and carefully among the stones which were lying about round the foundations of the new church, advanced as far as the fountain which, formed the centre of the piazza, erected in the very place where the obelisk is now set up of which we have spoken already; when he reached this spot he stopped, doubly concealed by the darkness of the night and by the shade of the monument, and after looking around him to see if he were really alone, drew his sword, and with its point rapping three times on the pavement of the piazza, each time made the sparks fly. This signal, for signal it was, was not lost: the last lamp which still kept vigil in the Vatican went out, and at the same instant an object thrown out of the window fell a few paces off from the young man in the cloak: he, guided by the silvery sound it had made in touching the flags, lost no time in laying his hands upon it in spite of the darkness, and when he had it in his possession hurried quickly away. Thus the unknown walked without turning round half-way along the Borgo Vecchio; but there he turned to the right and took a street at the other end of which was set up a Madonna with a lamp: he approached the light, and drew from his pocket the object he had picked up, which was nothing else than a Roman crown piece; but this crown unscrewed, and in a cavity hollowed in its thickness enclosed a letter, which the man to whom it was addressed began to read at the risk of being recognised, so great was his haste to know what it contained.
