Gwenda Reed is staying with Marple's nephew for a few days. During a play, Gwenda screams out when she hears a couple of words and later confesses to Miss Marple she fears she is losing her mind as she saw an image of a strangled woman named Helen. To make things worse, she is in England for the first time in her life but she recognises the house she bought for herself and her husband as if she had been there before. Miss Marple calms her down and wonders whether Gwenda has lived in England when she was a child, and if she witnessed a murder.

I enjoyed this story, not so much for the big revelation in the end but by enjoying Gwenda's investigation as it progresses. It is interesting to dig on the past, as some things are not meant to be remembered/discovered... Gwenda is strong and likeable, she made a great main character.
