“...both Tom and I adore detective stories. Isn't that so, Tom?" [Lady Brace]
"Right!" agreed her husband...."But they've got to be proper detective stories. They've got to present a tricky, highly sophisticated problem, which you're given fair opportunity to solve."
"And," amplified Virginia, "no saying they're psychological studies when the author can't write for beans."
"Correct!" her husband agreed again. "Couldn't care less when you're supposed to get all excited as to whether the innocent man will be hanged or the innocent heroine will be seduced. Heroine ought to be seduced; what's she there for? The thing is the mystery. It's not worth reading if the mystery is simple or easy or no mystery at all.”
