With an inward laugh he pushed open the door once more and stepped into the room. For the moment no one noticed him; the game was at its most palpitating stage; four shaggy heads met beneath the lamp and four pairs of eyes were gazing with rapt attention upon the intricate maze of the dominoes.

Blakeney walked quietly across the room; he was just midway and on a level with the centre table when a voice was suddenly raised from that tense group beneath the lamp: "Is it thou, friend Heriot?"

Then one of the men looked up and stared, and another did likewise and exclaimed: "It is not Heriot!"

In a moment all was confusion, but confusion was the very essence of those hair-breadth escapes and desperate adventures which were as the breath of his nostrils to the Scarlet Pimpernel. Before those four men had had time to jump to their feet, or to realise that something was wrong with their friend Heriot, he had run across the room, his hand was on the knob of the door—the door that led to the antichambre and to freedom.

Bompard, Desgas, Jeanniot, Legros were at his heels, but he tore open the door, bounded across the threshold, and slammed it to with such a vigorous bang that those on the other side were brought to a momentary halt. That moment meant life and liberty to Blakeney; already he had crossed the antichambre. Quite coolly and quietly now he took out the key from the inner side of the main door and slipped it to the outside. The next second—even as the four men rushed helter-skelter into the antichambre he was out on the landing and had turned the key in the door.

His prisoners were safely locked in—in Heriot's apartments—and Sir Percy Blakeney, calmly and without haste, was descending the stairs of the house in the Rue Cocatrice.

The next morning Agnes de Lucines received, through an anonymous messenger, the packet of letters which would so gravely have compromised Arnould Fabrice. Though the weather was more inclement than ever, she ran out into the streets, determined to seek out the old Public Letter-Writer and thank him for his mediation with the English milor, who surely had done this noble action.

But the old scarecrow had disappeared.
