It’s January 1915 when Detective Inspector Arthur Neil receives a strange letter in the post with a couple of newspaper clippings attached. The clippings describe two seemingly unconnected incidents of women drowning in their own bathtubs. The letter writer asks Detective Inspector Neil to dig a little deeper. And when he does, he unravels a case far darker than he ever imagined. Murder They Wrote with Laura Whitmore and Iain Stirling is available weekly on BBC Sounds.
