Hold your flying horses! Barnabas Tew and Wilfred Colby are back, and, once again, they're in a bit of a pickle. Barnabas and Wilfred, two earnest but bumbling Victorian detectives, travel through the Nine Worlds of Norse mythology, trying to stave off the impending end of the world – an event which the locals call Ragnarok. This time, however, the intrepid twosome has some help: a brave Viking seer named Brynhild and her flying horse. Can the two plucky detectives and the fearsome Brynhild outwit those who would bring about Ragnarok? Will they survive the harsh conditions and terrifying creatures of the Norse afterlife? Will they save the world…again?
