Mr Curtiss

In the novel A Murder is Announced, Mr. Curtiss was the Wesleyan Minister. He wouldn't let his child wear a plate on her teeth, as he said it was the Lord's Will if her teeth stuck out. Miss Marple confronted him and said: 'After all, you do trim your beard and cut your hair. It might be the Lord's Will that your hair should grow out.' He replied that it was quite different.

Dr Blacklock, the father of Letitia and Charlotte Blacklock, reminds Miss Marple of Mr Curtiss.
