Take by the nose? (6)
I believe the answer is:
snitch
I believe this clue is a double definition.
'take' is the first definition.
(snitching is a kind of taking)
'the nose?' is the second definition.
(thesaurus)
'by' acts as a link.
(Other definitions for snitch that I've seen before include "Police informer" , "Grass" , "Telltale (sl.)" , "Inform on, tell tales" , "Whistleblower (informal)" .)
