                                                            Soap Update: Family Businesses

        In the popular radio drama Family Business, things aren't looking good for the Black family. They own

The Full Moon restaurant, but a new restaurant called The Angel is taking all their customers. The Full Moon

also has serious money problems and relationships between the family members are getting worse every week.

For new listeners here's our guide to the main characters in radio's most popular drama.

       Lydia Blake and her husband Clive own The Full Moon restaurant. Lydia is bright and extremely stubborn,

and she's very worried about the restaurant. She wants to borrow some money from the bank-if she can't,

The Full Moon might have to close.

      Clive Black is the chef (厨师) at the Full Moon-but being married to Lydia isn't easy. He thinks she's

impatient and inconsiderate and would like to ask her for a divorce (离婚). But if he does, what will happen

to the restaurant he loves?

      Darren is the oldest of Lydia and Clive's three children (their other son, Nick, left the programme a year

ago. Darren works as a waiter in his parents' restaurant when he's not stealing cars or staying out all night.

The most dishonest and unreliable(不可靠的) member of the family, he's the one we love to hate.

      Kathy is Darren's lovely wife and mother of three-month-old Elizabeth. Kathy is quiet, easy-going and

unselfish, but does she have a secret past?

      Eve King is the owner of The Angel restaurant, which opened in the same street as The Full Moon last

month. Eve is attractive, ambitious and single.
