Robert Arnott

I can’t write a verified 100–120 word biography for “Robert Arnott” from the details provided. The identification (“likely the Scottish novelist and short-story writer”) and the attribution of *The Boxer Benny Lynch* are not sufficiently certain for me to state as fact without a reliable source, and there are multiple people with the same name. If you share a link to an authoritative reference (publisher page, library authority record, obituary, or official biography) confirming the author’s identity and works, I can produce a 100–120 word bio that sticks strictly to verified facts.
