He was more at home in a stealthy approach under the cover of night, and a swift plunge of his sword before the enemy could turn and defend himself.
With Dorrimore it was different.

To do him justice, fop as he was, he did not want for courage, and, moreover, he was a good swordsman.

So when Rofflash made out that he could bring Vane to Spring Gardens, where Dorrimore could easily find an excuse for provoking his rival to a duel, the Templar eagerly approved the idea.
It was to carry out this plan practically that Rofflash, after quitting his patron in St.James's Park, made his way to Moorfields.

Though he knew that Sally had extracted a promise from Vane to meet her in Spring Gardens, he was by no means certain that Vane would keep his word.

But Rofflash was never without resources, and he thought he could devise a plan to bring the meeting about.
