Characters from Rye thus observed in Argyle? (9)
I believe the answer is:
regularly
If this is the answer I cannot explain how the clue works.
Can you help me to learn more?
(Other definitions for regularly that I've seen before include "Steadily, unvarying" , "How shoes will appear in schooners" , "Often - at intervals" , "Evenly" , "at the same time" .)
