In The Murder at the Vicarage, Reverend Clement describes her as "a mixture of vinegar and gush". At some point before the events of this novel, she had lost a gill of picked shrimps, and Miss Marple had solved the mystery because it reminded her of something else involving a sack of coals.
In the short story The Case of the Perfect Maid, Miss Weatherby talks to Miss Marple in the post office, telling her about how Lavinia Skinner gave Gladys Holmes a written reference saying that she was willing, sober and respectable, but saying nothing about honesty. Miss Weatherby is of the opinion that this is significant. She also expresses the opinion that the Skinners will have difficulty finding another servant, and perhaps then Emily Skinner will have to "get up and do something".
