exposed

I'm a little stuck... Click here to teach me more about this clue!

'showing' is the definition.
(thesaurus)

'former attitude by detective' is the wordplay.
'former' becomes 'ex' (prefix meaning former or onetime).
'attitude' becomes 'pose' (attitude can mean a pose or stance).
'by' means one lot of letters go next to another.
'detective' becomes 'd' (this might be a standard abbreviation of which I'm unaware).
'ex'+'pose'+'d'='EXPOSED'

Can you help me to learn more?

(Other definitions for exposed that I've seen before include "in the nude" , "Like a dummy" , "Deprived of cover" , "Laid bare" , "vulnerable" .)

I've seen this clue in the Sydney Morning Herald.
