S06:É05 - S06:E05 - Birds of Prey

While Troy assists an attractive wildlife liaison officer with an investigation into the illegal sale of protected bird eggs, Barnaby travels to Midsomer Magna to investigate the sudden death of a man, who apparently drowned himself. While there was evidence he was desperately seeking to avoid bankruptcy, and had visited a local millionaire to get back his money from a scheme he had invested in, a post mortem reveals that he had been murdered. The two detectives soon find their investigations crossing over, when a man found to have an illegal collection of bird eggs, is also murdered, prompting concerns that the millionaire's scheme is being used to defraud many, and that someone is willing to kill to keep the scheme going.
