-
“My parsnip wine is really extra good this year. Dr Jellyfield always takes a glass when he comes—which isn’t very often, I’m pleased to say, because my health is always remarkably good.”
“That will not prevent me from drinking to it,” said Peter, disposing of the parsnip wine with a celerity which might have been due to eagerness but, to Harriet, rather suggested a reluctance to let the draught linger on the palate.
