I hear it’s possibly the most dangerous (8)

Ross

I believe the answer is:

hairiest

'the most dangerous' is the definition.

'i hear it's possibly' is the wordplay.
'possibly' indicates an anagram.
'i'+'hear'+'its'='ihearits'
'ihearits' anagrammed gives 'HAIRIEST'.

(Another definition for hairiest that I've seen is " Most hirsute or slangily difficult".)

I've seen this clue in The Times.
