I tried book #1 in the Mrs. Jeffries series by American author Cheryl Lanham under the pseudonym, Emily Brightwell.
And easy, fun read.
It was written 1993.
There are dozens of sequels.
The central character of this cozy historical mystery series is Mrs. Jeffries, who is a housekeeper by profession and along with her staff, secretly helps Inspector Witherspoon of the Scotland Yard to solve the murder mysteries taking place in and around Victoria, England.
In fact, Witherspoon is a nice guy. Well meaning. But basically slow witted. His housekeeper and staff do a lot of the investigating for him.
A cute premise.
I don’t need to continue, however.
