@flamewingman Generally no, but not all peers have an estate tied to the title and not all estates tied to titles are part of the peerage.
One problem is that not all peers with an estate have sustainably profitable estate and some can't offset the cost with their own income. Since this guy apparently doesn't work that'd be my guess here.
The mangaka's naming sense, as always, is... fantastical. These names, in particular, seem like something out of Cluedo.
Oh, btw, on page 31, the maids are said to be hastily readying the "customer room". I assume the original said 客室, which should have been translated as "guest room". 客 can mean both "guest" or "customer".
Also, "horse litter" → "horse manure", and "Lady Rose" would definitely not be addressed as "Master Rose".
@freakofnature Yes! I got through the first few pages and couldn't stop cracking up at all the names. It was like he looked at a box of crayons and chose names from that.
The culprit was a little bit obvious in this case, though it's not like I knew all of the methods used before they were revealed. It's just that the butler had by far the best chance to pull a trick at the time that he was parking the car.
This entire chapter is lampshading the whole "The Butler did it" joke, isn't it? The names are so bizarrely childish, straight out of a kids' book. The writer usually manages to make more sensible-sounding names...
