Broker interrupts Musk interrogation (7)

I believe the answer is:

skinter

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

'broker' is the definition.
('skint' can be a synonym of 'broke')

'interrupts musk interrogation' is the wordplay.
'SKINTER' is hidden in amongst the letters.
But, I'm uncertain how this is indicated.

Can you help me to learn more?
