S10:E03 - King's Crystal

Following the death of Alan King while on a business trip to China, the family company, King's Crystal, is in financial trouble. As plans to shut the Midsomer Magna factory are being put into action, Alan's wife Hilary and brother Charles are married in the village church - much to the dismay of Alan's son Ian. In addition to strife between members of the family, the factory workers are outraged at the loss of their jobs. So when company accountant Peter Baxter is found murdered, Barnaby and Jones suspect a disgruntled employee is to blame. But in order to investigate the matter further, Jones is forced to work undercover, and infiltrate the local group of Freemasons in the village.
