Brewster

In the Miss Marple short story The Thumb Mark of St. Peter, Brewster is the name of the nurse who was employed to look after old Mr Denman, the father of Geoffrey Denman.

Brewster was away on the night that Geoffrey Denman was taken ill and so had been unable to help.

Brewster was described as a "gaunt middle-aged woman of about fifty." Although her qualifications are not mentioned, there are some suggestions in the text that she is a qualified nurse. For example, Mabel Denman said that because Brewster was away, "there was no one who knew what to do" when Geoffrey Denman felt unwell. Brewster herself said that it was a pity she wasn't there. Miss Marple also asks her if being delirious was a symptom of ptomaine poisoning and she was able to give an informed answer.
