DI Goodman and the team are called in to investigate in the Saint Marie jungle, when a group of birdwatchers discover one of their party murdered. Visiting the island to catch a glimpse of the famous Saint Marie Green Parrot, the group found fellow ornithologist Marc Talbot stabbed with his own knife. Humphrey is fascinated by the case but equally perplexed when it is revealed that all of the suspects were in sight of each other when the crime occured. They begin at wondering how anyone could have had time to kill Marc in the few minutes between his leaving camp in plain sight and being found murdered at the watch-point. Desperate to find answers, Dwayne goes undercover to keep an eye on the key suspects; later, Fidel finds him battling through the undergrowth in the jungle to find one missing piece of evidence.
