Stowe provides further details about her story based on actual events in A Key to Uncle Tom’s Cabin.
As Eva grew sicker, she became more vocal about teaching the enslaved people on the St. Clare plantation to read. In her conversation with her mother, she expresses feelings about teaching them and bringing them to free states. In A Key to Uncle Tom’s Cabin, Stowe questions whether or not people are living up to their Christian values if they leave their fellow brethren behind.
