Today's DraculaDaily contains a nasty little nugget of antisemitism, in the form of one of the NPCs the Crew of Light bribes being specifically called out as Jewish and greedy.
...not to excuse Stoker's clear antisemitism, but some people might be wondering what the "Adelphi theatre type" he mentions is. Good news: It's probably less bad than you're thinking.
A brief google took me to Victorianweb.org, which is a pretty reliable source for information on the period. It's got a writeup of a lot of the minor theatres in London at the time, and it states:
"[The Adelphi] had more "tone" than the other minor theatres because its patrons in the main were the salaried clerks of barristers and solicitors."
It goes on to explain that the Adelphi specifically hosted a lot of plays by Dickens (and a lot of Dickens bootlegs) and a lot of burlettas (what we'd call comedy musicals today).
Stoker's saying "this guy is a little bit lower class than our heroes- probably in about the class position that Jonathan started out at, honestly- is an extremely bank-clerky bank clerk, and likes a good middlebrow comedy."
So yeah, calling this NPC "the Adelphi theatre type" is a bit like saying "you can tell just by looking at this guy that he trades crypto and has seen every fucking Marvel movie". (Not that much, but a bit.) Knowing that Stoker worked in theatre, it's a weird little bit of humanization in the middle of a super dehumanizing period-typical stereotype.
[ETA: @luanna801 pointed out in the notes that this could also mean "the type of antisemitic stock character one would see on stage at the Adelphi", like calling someone a Tyler Perry character. I don't know which interpretation is more likely to be accurate, but it's worth noting here.]
