So bold an adventurer, so keen an intriguer was sure to have scented the trap immediately, and if he appeared ready to fall into it, it was because there had already sprung up in his resourceful mind some bold coup or subtle counterplan, with which he hoped to gratify his own passionate love of sport, whilst once more bringing his enemies to discomfiture and humiliation.
Undoubtedly Sir Percy Blakeney, as an accomplished gentleman of the period, could not very well under the circumstances which had been so carefully stage-managed and arranged by Chauvelin, refuse the latter's challenge to fight him on the other side of the Channel.

Any hesitation on the part of the leader of that daring Scarlet Pimpernel League would have covered him with a faint suspicion of pusillanimity, and a subtle breath of ridicule, and in a moment the prestige of the unknown and elusive hero would have vanished forever.
But apart from the necessity of the fight, Blakeney seemed to enter into the spirit of the plot directed against his own life, with such light-hearted merriment, such zest and joy, that Chauvelin could not help but be convinced that the capture of the Scarlet Pimpernel at Boulogne or elsewhere would not prove quite so easy a matter as he had at first anticipated.
That same night he wrote a long and circumstantial letter to his colleague, Citizen Robespierre, shifting thereby, as it were, some of the responsibility of coming events from his own shoulders on to the executive of the Committee of Public Safety.
"I guarantee to you, Citizen Robespierre," he wrote, "and to the members of the Revolutionary Government who have entrusted me with the delicate mission, that four days from this date at one hour after sunset, the man who goes by the mysterious name of the Scarlet Pimpernel, will be on the ramparts of Boulogne on the south side of the town.

I have done what has been asked of me.

On that day and at that hour, I shall have brought the enemy of the Revolution, the intriguer against the policy of the republic, within the power of the government which he has flouted and outraged.

Now look to it, citizens all, that the fruits of my diplomacy and of my skill be not lost to France again.
