What Brighton's got is a major sea port on either side, good for importing drugs, great for exporting cash, stolen cars, stolen antiques. It's got the largest number of antique shops in the UK, so it's a great place to fence stolen goods. It's got tremendous communication: you've got the sea ports, you've got the channel tunnel, you've got Gatwick Airport 25 minutes away, and London's 50 minutes away by train. So all these escape routes... Which is what villains like.
