Open to fraud, ruin some textual analysis (14)

I believe the answer is:

deconstruction

'some textual analysis' is the definition.

'open to fraud ruin' is the wordplay.
'open to' is an insertion indicator.
'fraud' becomes 'con' (con is a kind of fraud).
'ruin' becomes 'destruction' (I've seen this before).
'con' going inside 'destruction' is 'DECONSTRUCTION'.

(Another definition for deconstruction that I've seen is " Method of critical analysis of literary texts".)

I've seen this clue in The Times.
