over the transom

The story

1. Latin · derived fromtrānstrum“crossbeam”
2. English todayover the transom

A transom is a lintel or crosspiece over a door; likely an alteration of Latin trānstrum (“crossbeam”). Refers to the idea of a writer tossing a manuscript through the open window over the door of the publisher's office. Alternatively, a "transom" is the nautical term for the back of a small boat. Something which "came in over the transom" would have suddenly (and presumably, surprisingly) entered through the "back door" of the craft, metaphorically.
