Basic Murder Babes is a true crime show built on a contrast between two sisters. Sierra introduces herself as the host and loves spooky material. Her co-host Cheyenne is her baby sister, only 11 months younger, and gets introduced as the scaredy cat. Cheyenne likes Christmas more than Halloween and princesses more than villains. She says she is not the biggest fan of murder but does not mind hearing the stories. The show's own welcome sets the terms: a little drinking, a lot of talking, and some weirdness. More than one opening stops on what is in each glass, such as a favourite cider finally found in a six-pack, or Moscato in a tumbler with a straw so the wine will not stain teeth. Then the stories begin, and they are grim. One episode is billed as a return to the show's roots: an infamous serial killer chosen at a listener's request. It includes a white box van with windows too dark to see through, which the hosts call the reason anyone walking alone panics at the sight of a white van. Another serial killer case runs across multiple parts. The hosts pause over a survivor who lost her dancing career before moving on to his first confirmed murder. A December run sorts holiday crimes under the seven deadly sins, offered for Christmas, Hanukkah, Kwanzaa or any other December tradition. The titles show the scheme: 'CALL 59: Holiday Pride', 'CALL 60: Holiday Envy', 'CALL 61: Holiday Gluttony/ Holiday Lust' and 'CALL 62: Holiday Greed'. That run includes a mother who drugged her children with opiates, a woman found beneath her own Christmas tree among presents wrapped for her grandchildren, and a daughter who shot her father on Christmas Eve. The reactions are blunt. When a woman in one case shoots the ex-boyfriend who is driving her, the hosts point out their own sarcasm about how logical that was. Small asides fill the gaps: the internet's 'Christmas Adam', a Star Wars ugly sweater, one sister's hockey against the other's football. The co-host seat is not always Cheyenne's, and in 'CALL 59: Holiday Pride' Sierra is joined by Kelsey. One episode notes that case photos go up on the show's website and posts, and explains when a victim's picture could not be found. Several episodes close with pointers to email, social accounts and a Patreon offering ad-free episodes. One sign-off, 'peace over murder', sums up the mix. What a listener gets is grim casework told in the loose, joking style of two sisters talking over drinks.
