Amos Parker

In the novel The Sittaford Mystery, Amos Parker is a tradesman, likely to be a grocer, with a business in the town of Exhampton, six miles from the village of Sittaford on the northern edge of Dartmoor.

According to the gossipy Mrs Curtis, Mrs Willett and her daughter Violet Willett, the tenants of Sittaford House, bought their groceries from Amos Parker. According to Mrs Curtis, the Willett's "weekly book" (the amount spent on groceries a week) came to well over eight or nine pounds (equivalent to over a hundred pounds in 2020). Mrs Curtis said that one could not believe the number of eggs which they bought.
