'ice-cold enemies round the corner' is the definition.
I can't judge whether this definition defines the answer.

'ice-cold enemies round' is the wordplay.
'ice cold' becomes 'l' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'enemies' becomes 'foes' (I've seen this before).
'round' means one lot of letters goes inside another.
'l' going into 'foes' is 'FLOES'.
