In page Thomas B. Costain:

"

In 1940, he wrote four short novels but was "enough of an editor not to send them out". He next planned to write six books in a series he called "The Stepchildren of History". He would write about six interesting but unknown historical figures. For his first, he wrote about the seventeenth-century pirate John Ward aka Jack Ward. In 1942, he realized his longtime dream when this first novel For My Great Folly was published, and it became a bestseller with over 132,000 copies sold.[5] The New York Times reviewer stated at the end of the review "there will be no romantic-adventure lover left unsatisfied." In January 1946 he "retired" to spend the rest of his life writing, at a rate of about 3,000 words a day.[citation needed]
