Ace detectives finding LSD (4)

Ross

I believe the answer is:

acid

'lsd' is the definition.
(synonyms)

'ace detectives' is the wordplay.
'ace' becomes 'a' (abbreviation).
'detectives' becomes 'CID' (abbreviation for Criminal Investigation Department).
'a'+'cid'='ACID'

'finding' acts as a link.

(Other definitions for acid that I've seen before include "Opposite of alkali; sour" , "Sour, sharp-tasting" , "Drug, tart" , "bad rain" , "Biting - tart" .)

I've seen this clue in The Sun.
