the Barons was translated into Russian and sold immensely well there; his next work, Comrades for the Charter was less successful but Cue for Treason in 1940 proved enduringly popular and remains his best known work.

He authored a guide aimed at teaching creative writing to young adults, The Young Writer: A Practical Handbook. He wrote three books of autobiography: A Whiff of Burnt Boats (1971), Laughter at the Door (1974), and in the last year of his life, the final part, Farewell the Hills. This was written for his family and friends, and published privately after his death. Trease was an acknowledged influence on author Hester Burton and inspired others, including Rosemary Sutcliff and Leon Garfield. While in some ways they outpaced him, he continued to write and published 113 books before "calling it a day" at the age of 88 because of illness. Many were translated for foreign markets, including Asia and Europe.
