Are you a reader who loved "The Man in the Brown Suit" but found it sorely lacking in English country homes? Well, fear not, because this week's episode tackles a Christie novel overflowing with rose gardens, secret passageways, and... chimneys. Does the novel also bear a somewhat suspicious similarity to the plot of our last novel? It does! Join us as we explore this similarity, as well as the intricacies of fictional Balkan geopolitics, diamond thievery, and... chimneys... in this, Superintendent Battle's first case.
