Following the big finale today on PBS, when can we expect more news regarding The Marlow Murder Club season 3? Well, as you would imagine, there are a few different things worth noting here — but we should start by noting another chapter is 100% coming. This is a renewal that was actually revealed in the spring, long before season 2 even premiered! As for when the next season is going to premiere, our general feeling is that at some point in the summer or fall of next year. What do you most want to see moving into The Marlow Murder Club season 3 when it arrives?
