How the clue works
So Serious crime is your definition — a capital offence is about as grave as it gets. The clever bit is the rest: "criminal's money" hints at CAPITAL (money) OF FENCE, where a fence is someone who deals in stolen goods, i.e. a criminal. Read it as "capital of fence" and you've got your answer.
