Liz Roper

Liz Roper is a name that doesn't match what's reliably known about Susan Brown's work on Broadchurch — she is best known there as Maggie Radcliffe, the local newspaper editor. I don't have confident, accurate details about a character called Liz Roper to describe honestly.

Since I can't verify this character or role with confidence, I'd rather say so than invent traits, dialogue, or a place in the story that might not exist. A guess dressed up as knowledge would do a disservice to both the show and the actor.
