Roberts (Why Didn't They Ask Evans?)

In the novel Why Didn't They Ask Evans?, Roberts is the husband of Gladys who is the housekeeper at the vicarage in Marchbolt. Not much is said about Roberts except that he and Gladys together "ran" the vicarage, suggesting that he is a gardener or some sort of handyman.

ITV's Agatha Christie's Marple
In the 2008 ITV adaptation, the "Florence", (renamed from Gladys) housekeeper of Marjorie Attfield is also married to Roberts. Roberts does not appear on screen but Florence tells Miss Marple that she is happily married to him and that he is a wonderful husband who treats her like a queen.
