“Memory is a motherfucker,” detective Rufus Cotesworth (Mandy Patinkin) declares in Hulu’s Death and Other Details. Humans, he means, are prone to accidental forgetfulness, self-indulgence, and, on occasion, trauma-driven memory loss. How, then, will Rufus, the so-called “World’s Greatest Detective,” crack a case that relies on both his own and witnesses’ memories over the last 20 years?

The inciting incident is the murder of entitled richling Keith Trubitsky (Michael Gladis) aboard a luxury ocean liner, establishing an Agatha Christie-style closed circle of suspects, as the killer must be on the ship. Trubitsky, it turns out, was invited as a friend of the Colliers, whose family business is on the brink of financial ruin. They chartered the boat as a last-ditch attempt to schmooze potential investors, the Chun family, who’ve hired Rufus to do due diligence.

Rufus has his own agenda: to finally solve the 20-year-old murder case of the Colliers’ former assistant.
