I didn't think I'd care this much about saying farewell to Parker Pyne, heart specialist.... Fortunately, there is a LOT to discuss in this jam-packed (really, pilchard-packed) episode: hot mackerel, plasticine, and corncrakes, for starters. Eternal thanks to Dr. Michelle Kazmer for lending her voice and expertise on this episode. If it isn't the sendoff Parker Pyne deserves, it's because Michelle was way too kind and smart for him. Just saying.
