I think that the climax would be when the identity of the Scarlet Pimpernel is revealed.

The climax and denouement of The Scarlet Pimpernel surprisingly is devoid of any physical combat or face-to-face action. Indeed, more than an adventure novel, we seem to have wandered into the espionage genre, where the goal is to evade, conceal, and ambush rather than embrace man-to-man combat. Furthermore, just as the end of each chapter in Orczy's novel relies on the dangling hook, the final machinations of the plot depend on the creativity and uniqueness of Percy's stratagems. We fully expect his escape -- but the question is whether we can predict or anticipate the nature of his plans.
