Victorian style pack?

Maybe for shoots and giggles, they add their own mystery duo? In that time, it was so easy to commit crimes and not get caught. With the difficulty in getting money, there's no telling what the Sims do to survive. It would add much to the lore.

I have read, however, that Sherlock was not actually some brilliant detective, no. In the contrary, he was a representation of what detectives back when were like. They had to know everything about everyone... however, the lack of modern crime fighting sciences we have now, it was easy to even kill without getting found out.

Not that they would add murder- unless, of course, the player does it- but an increase in crime would make it come alive- theft, vandalism, whatever.
