Crimes one flies from perhaps (8)

I believe the answer is:

felonies

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

'crimes' is the definition.
(felony is a kind of crime)

'one flies from perhaps' is the wordplay.
'one flies' anagrams to 'FELONIES'.
But, I am unsure how this is indicated.

Can you help me to learn more?

(Another definition for felonies that I've seen is " Serious crimes (esp. USA)".)

I've seen this clue in The Globe and Mail.
