Fifteen years later, she completed her second novel "The Lost Traveller", which was published in 1950. In the subsequent five years, after undergoing treatment for mental illness and reconverting to Catholicism, she completed the Clara Batchelor trilogy, which includes "The Lost Traveller", about her relationship with her mother and father, "The Sugar House", about her first unconsummated marriage, and "Beyond the Glass", about an intense love-affair followed by a breakdown, which is vividly described. As with her previous work, the trilogy was fictional, but mainly autobiographical. The four novels together narrate her life from ages 9 to 23. In 1966, she published a collection of letters entitled "The Hound and the Falcon: The Story of a Reconversion to the Catholic Faith". She wrote "Three in a Room", a three-act comedy, as well as many short stories, poems and juvenile fiction.
