[4] After divorcing, Bishop lived in Cleveland, Ohio working as a court reporter and studying journalism at Columbia.

Among her works are three horror stories she wrote in collaboration with H. P. Lovecraft ("The Curse of Yig", "Medusa's Coil", and The Mound).

The Mound and The Curse of Yig were based on local stories she learnt while visiting her sister's farm in Oklahoma.

In 2014, a hitherto unknown and unpublished cache of thirty-six letters from Lovecraft to Bishop was discovered.

The letters had once been kept in a trunk with her manuscripts at the home of Jeanette Starkweather Cole, with whom Zealia had moved in after the death of her husband D.W. Bishop in 1956.

The trunk was initially bequeathed to their daughter, Etha Charmaine Cole McCall Fowler (Zealia's great niece).
