Truly Fabulously Monstrous is run by Hattie James and Ace, who each introduce themselves as half of the host. It is a fitting introduction for a show built on back-and-forth. In each episode one of them brings a story, and the other hears it out, cutting in with questions, jokes and verdicts. The stories fall into two broad camps. One is crime. Robert Durst appears as a multimillionaire Texas fugitive caught in Pennsylvania for shoplifting a sandwich and a newspaper, a detail the hosts turn over with open disbelief. Another case goes back to an 1870 affair between Christiana and Dr. Beard, and the hosts are clear about whom they blame: the man with the power. The moment that sticks is Christiana visiting his wife with a gift of chocolates, a gesture one host reads as extremely petty and professes to live for. The other camp is the unexplained. Lake Champlain's Champ gets a full file: a witness estimating a creature 25 to 35 feet long, a steamship said to have run into it, and P.T. Barnum offering a reward for its hide. The hosts are blunt about Barnum. Another episode gathers sea creature reports, including one from four men from Red Bank, New Jersey, in 1889, and asks whether the witnesses saw only a head and a tentacle of a giant squid. That instinct for a plain explanation shows up elsewhere too, as when the storm-calming legend of St. Nicholas prompts an aside on weather as a science of probability and pattern recognition. Holidays get their own episodes. Besides St. Nicholas, there is a Halloween special on the 1938 War of the Worlds broadcast, which detours to a Dracula production where Orson Welles rejected a cabbage struck with a sharpened broomstick as much too leafy. The research is visible throughout. The hosts quote their sources, point listeners to Scientific American through interlibrary loan, and say plainly when the record has nothing more to add. The episode titles carry the same humor: 'Torsos Are The Wurst', 'Santa's Bone Juice', 'That's a Pike, Samuel'. None of it starts cold. Episodes open on personal catch-up: a cat's health scare, another cat batting a plastic toy tower across the room, a long Halloween, a household mishap. The show runs in seasons, and those openings make each episode feel like rejoining a conversation already under way.
