Mrs Jeffries Plays The Cook [EPUB ebook] 

One of London’s best known (and least liked) businessmen is murdered, and once again Mrs Jeffries has to help the Inspector solve the case. This charming series of Victorian murder mysteries features mild-mannered Inspector Witherspoon of Scotland Yard and, more importantly, Mrs Jeffries, his housekeeper. A policeman’s widow herself, her quick wits allow her to nudge the Inspector in the right direction to solve the crime.
