Rose Cottage (Mrs McGinty's Dead)

In the novel Mrs McGinty's Dead, Rose Cottage is the former home of Eva Selkirk in the village of Broadhinny. She lived there until she married Guy Carpenter some three months before the events in the book. Mrs McGinty worked there as a cleaner, and came there every Friday.

Poirot discovered this in his research and used it to counter Mrs Carpenter's claim that she never knew Mrs McGinty.
