Charles Dickens, A Christmas Carol, 1843

"If we were not perfectly convinced that Hamlet's Father died before the play began, there would be nothing more remarkable in his taking a stroll at night, in an easterly wind, upon his own ramparts, than there would be in any other middle-aged gentleman rashly turning out after dark in a breezy spot--say Saint Paul's Churchyard for instance--literally to astonish his son's weak mind."
