The Mezzotint from "Ghost Stories of an Antiquarian" by M. R. JamesĀ 

A parcel of any kind always arrives a day later than you expect it, and that of Mr Britnell proved, as I believe the right phrase goes, no exception to the rule. It was delivered at the museum by the afternoon post of Saturday, after Mr Williams had left his work, and it was accordingly brought round to his rooms in college by the attendant, in order that he might not have to wait over Sunday before looking through it and returning such of the contents as he did not propose to keep. And here he found it when he came in to tea, with a friend.
