Followed the girl in, you conclude (6)
I believe the answer is:
ensued
'followed' is the definition.
(I've seen this before)
'the girl in you conclude' is the wordplay.
I cannot really see how this works, but
'girl' could be 'sue' and 'sue' is located in the answer.
'conclude' could be 'end' (I've seen this before) and 'end' is found within the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ensued that I've seen before include "Happened in consequence" , "Resulted, followed" , "Followed as a consequence" , "Befell" , "Happened afterwards or as a result" .)
