Michael Ellacott is the father of Robin and her three brothers, Stephen, Martin and Jonathan. Michael is married to Linda, and they live in Masham, where they raised their family. He has a chocolate Labrador called Rowntree. (Rowntree is the name of a local company in Yorkshire that produces sweets, including chocolate. Now owned by Nestle, Rowntree created the Kit Kat, Aero, Smarties and Rolo candies.)
The only physical description we have of him in the books mentions that he wears glasses, probably reading glasses, as they’re positioned “halfway down his nose.” We think the actor cast in the role of Michael Ellacott, Paul Butterworth, looks exactly like Robin’s dad should look:
In The Silkworm, Michael sleeps in the living-room armchair while Robin, Matthew and Linda watch a television interview of Michael Fancourt.
