The Gatehouse Mystery

The mystery is almost secondary compared to the antics of the kids.
The number and types of servants in Honeys house is bewildering.
For a family of 4 including 2 teenage children, do they really need 7-8 full-time staff that live in the house?
Also, it's kind of weird how excited Honey is to have a little job and earn some money.
I am way out of the target audience but it was somewhat entertaining.
