In this excerpt from Emmuska Orczy's novel The Scarlet Pimpernel, which line best represents an element of historical fiction?

They were mostly fisher-folk who patronised Mr. Jellyband's coffee-room, but fishermen are known to be very thirsty people; the salt which they breathe in, when they are on the sea, accounts for their parched throats when on shore, but "The Fisherman's Rest" was something more than a rendezvous for these humble folk.

Hope my answer would be a great help for you.
