Playwright producing page by and by (6)
I believe the answer is:
plater
'playwright' is the definition.
(Alan Plater was an English playwright)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for plater that I've seen before include "cook?" , "horse entered in minor race" , "Alan, playwright" , "Worker who coats articles with a film of metal" .)
