What's your poison? Fethering residents, Jude and Carole, get more than they bargained for when a lunchtime meal in their local pub leaves everyone with food poisoning. The landlord is horrified and when a series of disasters start to befall his business it looks like it could be the end of the road for the Crown and Anchor. Left with a bad taste in their mouths – and not just from the food – the two amateur detectives wonder if it might just be more than a run of bad luck, which is forcing their favourite pub into bankruptcy. When Ray, a young man with the mental age of a five year old, is found in the kitchen of the pub with a knife through his heart – Carole and Jude swing into action. There's a killer on the loose in Fethering and our lady sleuths need to uncover who it is before it's last orders for the pub – and themselves.
