“There is no detective in England equal to a spinster lady of uncertain age with plenty of time on her hands.”
“It was easy, terribly easy, to become with time a middle-aged spinster with a sharp tongue. She would have to guard against this.”

“She was "a woman of uncertain age.”
“There was a teapot, in which Mma Ramotswe -- the only lady private detective in Botwana -- brewed tea. And three mugs -- one for herself, one for her secretary, and one for the client. What else does a detective agency really need?”
“Be equal to your talent, not your age. At times let the gap between them be embarrassing.”
