Reminiscent of detective finally addressing case (9)
I believe the answer is:
evocative
'reminiscent of' is the definition.
(synonyms)
'detective finally addressing case' is the wordplay.
'finally' indicates one should take the final letters.
'addressing case' becomes 'vocative' (grammatical case for addressing someone).
The final letter of 'detective' is 'e'.
'e'+'vocative'='EVOCATIVE'
(Other definitions for evocative that I've seen before include "Drawing forth" , "Evoking deep memories" , "Thought-provoking" , "recalling the past" , "summoning up bygone age" .)
