'seen in pursuit?' is the definition.
'quest' can be an answer for 'pursuit?' (synonyms). I'm not sure about the 'seen in' bit.

'what french saint' is the wordplay.
'what french' becomes 'que' ('what' in French).
'saint' becomes 'st' (abbreviation).
'que'+'st'='QUEST'

'is' is the link.

(Other definitions for quest that I've seen before include "Long or arduous search" , "Mission" , "Prolonged search" , "Pursuit" , "Hunt, goal" .)
