Showing The Queen of the Tambourine by Jane Gardam

Eliza Peabody is one of those dangerously blameless women who believes she has God in her pocket. She is too enthusiastic; she talks too much. Her concern for the welfare of her wealthy South London neighbours extends to ingenuous well-meaning notes of unsolicited advice under the door.

It is just such a one-sided correspondence that heralds Eliza's undoing. Did her letter have something to do with the woman's abrupt disappearance ? Why will no-one else speak of her? And why the watchful, pitying looks and embarrassment that now greet her?
