Crossword Genius

In which theatrical gossip is conveyed? (5,8)

Ross

I believe the answer is:

event location

I'm a little stuck... Click here to teach me more about this clue!

'in' is the definition.
(I know that in can be written as event location)

'theatrical gossip is conveyed?' is the wordplay.
I cannot really understand how this works, but
'gossip' could be 'cat' (cat is a kind of gossip) and 'cat' is located in the answer.
This may be the basis of clue (or it may be nonsense).

'which' acts as a link.

Can you help me to learn more?
