The offence of one coming to light (5)

Ross

I believe the answer is:

arson

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

This might be a double definition.

'the offence' is the first definition.
(crime of illegally starting a fire)

'one coming to light' is the second definition.
I know that 'light' relates to this answer. I also know that both the answer and definition are singular nouns

'of' acts as a link.

Can you help me to learn more?

(Other definitions for arson that I've seen before include "burning problem" , "Malicious fire-raising" , "Crime of fire-setting (5)" , "Crime involving fire" , "serious offence" .)
