Molly works as a maid at the Regency Grande Hotel and is very proud of her job: she enjoys it, is very methodical and perfectionist, and above all, she feels protected by the hotel’s rules of etiquette. These rules, which she learns in staff training meetings, together with the wise advice of her grandmother, help her compensate for her lack of social skills, which makes her an extremely naive person who is unable to interpret people’s gestures.
Molly, without realizing it, becomes involved in a murder case at the hotel and will have to prove her innocence, relying on what she has learned from her grandmother in order to distinguish good friends from “rotten apples,” as she puts it.
A very entertaining and gripping novel, with many good and sound lessons; but towards the end of the novel two ideas appear that darken this: a case of assisted euthanasia and the suggestion of a truth that may be relative.
