After getting bail somehow, I find an excuse (5)
I believe the answer is:
alibi
'an excuse' is the definition.
(excuse given by a suspect in an investigation)
'after getting bail somehow' is the wordplay.
'after' becomes 'i' (I can't justify this - if you can you should give a lot more credence to this answer).
'getting' is a charade indicator (letters next to each other).
'somehow' indicates anagramming the letters.
'bail' anagrammed gives 'alib'.
'i' after 'alib' is 'ALIBI'.
'i find' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for alibi that I've seen before include "It shows one wasn't at crime scene" , "Defence used by an accused person" , "Story confirming innocence" , "A claim one was elsewhere when crime took place" , "that gets him off the hook?" .)
