English story's upset secretive folk (7)
I believe the answer is:
oysters
'english story's upset secretive folk' is the definition.
I can't tell whether this defines the answer.
'english story's upset' is the wordplay.
'english' becomes 'E' (abbreviation).
'upset' is an anagram indicator.
'e'+'storys'='estorys'
'estorys' with letters rearranged gives 'OYSTERS'.
Can you help me to learn more?
(Other definitions for oysters that I've seen before include "Yet Ross has these strange marine creatures" , "Shy people" , "Edible bivalve molluscs" , "Yet Ross can find the marine creatures" , "Tasty pearl-producing bivalves" .)
