Mordaunt replied by trying his opponent’s weapon with an amount of strength which the Gascon was astonished to find in a form apparently so feeble; but thanks to a parry no less clever than that which Mordaunt had just achieved, he succeeded in meeting his sword, which slid along his own without touching his chest.

Mordaunt rapidly sprang back a step.

“Ah! you lose ground, you are turning? Well, as you please, I even gain something by it, for I no longer see that wicked smile of yours. You have no idea what a false look you have, particularly when you are afraid. Look at my eyes and you will see what no looking-glass has ever shown you—a frank and honorable countenance.”

To this flow of words, not perhaps in the best taste, but characteristic of D’Artagnan, whose principal object was to divert his opponent’s attention, Mordaunt did not reply, but continuing to turn around he succeeded in changing places with D’Artagnan.

He smiled more and more sarcastically and his smile began to make the Gascon anxious.

“Come, come,” cried D’Artagnan, “we must finish with this,” and in his turn he pressed Mordaunt hard, who continued to lose ground, but evidently on purpose and without letting his sword leave the line for a moment. However, as they were fighting in a room and had not space to go on like that forever, Mordaunt’s foot at last touched the wall, against which he rested his left hand.

“Ah, this time you cannot lose ground, my fine friend!” exclaimed D’Artagnan. “Gentlemen, did you ever see a scorpion pinned to a wall? No. Well, then, you shall see it now.”

In a second D’Artagnan had made three terrible thrusts at Mordaunt, all of which touched, but only pricked him. The three friends looked on, panting and astonished. At last D’Artagnan, having got up too close, stepped back to prepare a fourth thrust, but the moment when, after a fine, quick feint, he was attacking as sharply as lightning, the wall seemed to give way, Mordaunt disappeared through the opening, and D’Artagnan’s blade, caught between the panels, shivered like a sword of glass. D’Artagnan sprang back; the wall had closed again.

Mordaunt, in fact, while defending himself, had manoeuvred so as to reach the secret door by which Cromwell had left, had felt for the knob with his left hand, pressed it and disappeared.

The Gascon uttered a furious imprecation, which was answered by a wild laugh on the other side of the iron panel.
