What might follow rag-tag old baronet detained by security? (7)
I believe the answer is:
bobtail
'what might follow rag-tag' is the definition.
I can't judge whether this definition defines the answer.
'old baronet detained by security?' is the wordplay.
'old' becomes 'o' (abbreviation).
'baronet' becomes 'bt'.
'detained by' means one lot of letters goes inside another (I've seen this in other clues).
'security?' becomes 'bail' (I've seen this in another clue).
'o'+'bt'='obt'
'obt' placed inside 'bail' is 'BOBTAIL'.
Can you help me to learn more?
(Other definitions for bobtail that I've seen before include "Rag, tag and ..." , "Stump behind" .)
