"

The normally prolific Eberhart wrote relatively few books in the 1940s, possibly due to upheaval in her personal life.[1] After 20 years of marriage, she divorced Alanson Eberhart, and in 1946 married John Hazen Perry.[2] But within two years, she had divorced Perry and remarried Eberhart.[3][4] The Eberharts remained married until his death in 1974.[citation needed]
