Sarah Keate is a fictional character, the protagonist in a series of medical mystery novels by American author Mignon G. Eberhart.
[3][4] In fact, Keate proved to be Eberhart's only series sleuth, as the prolific author switched in the mid-1930s to writing mostly standalone novels, with no recurring characters.
As an amateur sleuth, Keate gets involved in situations that are "closed community" mysteries, with a finite number of potential suspects.
However, in between discovering interesting objects, attending inquests and pursuing suspects, Miss Keate carries out the duties of a nursing supervisor efficiently and without complaints.
[6] The second Nurse Keate novel won a $5000 Scotland Yard Prize, from the Crime Club booksellers association.
