How do you make a show about a trio of true crime podcasters without inviting unfavourable comparisons to Only Murders in the Building? The answer is you don’t. Lest we forget, Steve Martin and John Hoffman’s mesmerising comedy is up there with the best of them. What separates it from the pack is that it works as both a satirical send-up of America’s demented true-crime industry, and as a playful murder mystery in its own right.
