Lady Everbourne-Finch is hosting her annual family and friends get together at her estate in Scotland. The celebrations are in full flow when a horrified party guest discovers the Lady has been murdered. Panic ensues and the guests realise they are all suspects. They call a fixer who remedies difficult situations for the super rich. He sends a detective pair to the house – a father and son team. The guests think it’s a joke when they see the son. He’s 12. He’s also a genius who sees the world differently to the rest of the world. His father is an expert in body language. Can they find the murderer before more people die?
