Smaller missions can have their appeal. Be it for time constraints or if you just don´t want to explore for some hours.
"A House Call" however is not really a pleasant mission. The design of the mansion is ok, nothing to say against that. But some of the loot is hidden too well and therefore I ended up with the bare minimum of 751(1 gold piece more than needed on highest difficulty).
There is also a kinda annoying restriction that you can´t KO the antagonist and after the plot twist you are expected to to - exactly that. Yeah well.
The riddle is also a bit annoying to solve. The idea behind it is not bad, but the execution...and yes, you have to wait for antagonist to be not in the room, because he patrols his rooms.
Give it a try if you want, but don´t expect too much.
