Obligatory Umberto Eco plug: https://en.wikipedia.org/wiki/The_Island_of_the_Day_Before

Hopefully Eco + the title is enough but if it helps IMO it’s arguably his best work. All of the stepwise logic leading to madness of Name of the Rose and Foucault’s pendulum, a somewhat less slapstick sensibility than either, without descending into dryness as his later work. Super recommended.
