'one in uniform' is the definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.

'terrible danger with yours truly' is the wordplay.
'terrible' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'yours truly' becomes 'me' (the person who set this crossword).
'danger' with letters rearranged gives 'gendar'.
'gendar'+'me'='GENDARME'

'following' is the link.
