'put the lid on things' is the definition.
I can't judge whether this defines the answer.

'see too much' is the wordplay.
'see' becomes 'c' (the word for the letter, according to Chambers).
'too much' becomes 'over' (I've seen this in other clues).
'c'+'over'='COVER'

'and' is the link.

Can you help me to learn more?

(Other definitions for cover that I've seen before include "Shroud" , "Overlay" , "(Put) lid (on) - fielding position - insurance" , "Deal with" , "Disguise" .)

I've seen this clue in the Evening Standard.
