4:50 from Paddington (Miss Marple, #8)

by Agatha Christie

Everybody in St. Mary Mead knew Miss Marple; fluffy and dithery in appearance, but inwardly as sharp and as shrewd as they make them.

Though in speech Miss Marple was woolly and diffuse, in mind she was clear and sharp.

I haven’t got the physical strength nowadays to get about and do things.”
