Carson first met Dorothy Freeman in the summer of 1953 in Southport Island, Maine. Freeman had written to Carson welcoming her to the area when she had heard that the famous author was to become her neighbor. It was the beginning of an extremely close friendship that would last the rest of Carson's life. Their relationship was conducted mainly through letters, and during summers spent together in Maine. Over the course of 12 years, they would exchange somewhere in the region of 900 letters. Many of these were published in the book "Always, Rachel", published in 1995 by Beacon Press.
