Crossword Genius

Her best lead is lost then found again (2-11)

Ross

I believe the answer is:

re-established

'found again' is the definition.
(found can mean to establish)

'her best lead is lost' is the wordplay.
'lost' indicates an anagram.
'her'+'best'+'lead'+'is'='herbestleadis'
'herbestleadis' with letters rearranged gives 'RE-ESTABLISHED'.

'then' is the link.

I've seen this clue in The Guardian.
