Joan Croft

In the novel A Murder is Announced, Joan Croft is mentioned as being a quite masculine woman living in St. Mary Mead. She used to smoke cigar or pipe. When there was a holdup at the bank, she knocked the burglar down and took his pistol.

Diana Harmon is of the opinion that Joan Croft is a parallel of Phillipa Haymes. However, Miss Marple does not confirm this.
