Karen Slocombe isn't sure why she visited the supermarket that day -- as a member of the Food Chain Group and a stallholder at local farmers' markets, SuperFare is a place she would normally avoid. Luckily for Karen, she leaves moments before a bomb explodes, destroying the front of the store. Only a few days later, while manning her stall at Bradbourne Farmers' Market, Karen finds herself in the midst of another horrific crime. Peter Grafton, a fellow stallholder, is murdered in front of her. Despite the attack taking place in a busy town center, no one saw anything suspicious and the motive appears to be a complete mystery. When friends from the Food Chain Group start warning Karen not to tell the police certain details, her suspicions are instantly aroused. Could the two events be linked? And are Karen's friends involved?
