Ethel Merridew

In the novel At Bertram's Hotel, Lady Ethel Merridew is among the people Miss Marple remembered nostalgically while wandering in the streets of London. Lady Merridew was a distant cousin of Miss Marple. She used to live in a stylish house in Lowndes Square. Since then the house had been replaced with  a vast skyscraper building of modernistic design.
