Now, Jack really had no particular reason to care so much about said Duke—he was an evil rich man, but there were many of those. However, at one point when he’d been stupefied by Eliza, he had volunteered to kill that Duke one day. This was the closest he’d ever come to having a purpose in life (supporting his offspring was tedious and unattainable), and he had rather enjoyed it. D’Arcachon had now been so helpful as to reciprocate by attempting to hunt him down to the ends of the earth. Jack took a certain pride in that, seeing in it what his Parisian friend St.-George would call good form. To slink away now and live like a rat in East London, forever worrying about the Duke’s homicidal intentions, would be bad form indeed.
