Arthur M. (Arthur Merton) Harris

Arthur Merton Harris (1883–1945) was an American writer whose surviving library and public-domain records connect him with legal writing as well as narrative nonfiction. He is credited with works including Letters to a Young Lawyer, Harris' Justice of the Peace Guide for the State of Washington, and Pirate Tales from the Law.

Those titles give a good sense of his range. Some were practical books for legal readers, while Pirate Tales from the Law turned to courtroom records and maritime history, showing an interest in how real cases could be told as vivid stories.

Reliable biographical detail about his personal life appears to be limited in the sources I could confirm, so it is safest to remember him mainly through his books: a lawyerly author with a clear attraction to legal history, instruction, and the drama of old cases.
