It is, among other things, the title of a poem written by poem by John Francis O'Donnell 1861, the title of a tune written by Robert Ambrose in 1876, the title of a chapter in the Wind in the Willows, and the Latin school song of Winchester College. Here it seems to resonate with the sense of homecoming after reorganization and the intrusion of corrupt leadership, as well as Morse's arrival at the home that is familiar from the Inspector Morse series.
