Christie published six mainstream novels under the name Mary Westmacott, a pseudonym which gave her the freedom to explore "her most private and precious thoughts.” Interestingly enough, these books typically received better reviews than her detective and thriller fiction. Of the first, Giant's Bread published in 1930, a reviewer for The New York Times wrote, "... her book is far above the average of current fiction, in fact, comes well under the classification of a 'good book'. And it is only a satisfying novel that can claim that appellation." After her authorship of the first four Westmacott novels was revealed by a journalist in 1949, she wrote two more, the last in 1956. The other Westmacott titles are: Unfinished Portrait (1934), Absent in the Spring (1944), The Rose and the Yew Tree (1948), A Daughter's a Daughter (1952), and The Burden (1956).
