El problema final: Story, Cast and Series Facts

Story and premise

In the spring of 1959, thirteen people were stuck by a violent storm on a small islet near Mallorca. Any of them could anticipate what is about to happen at the small hotel where they're staying: Elisa Mander, a discreet British tourist, is found dead. What initially seems like a suicide soon raises unsettling signs—it may in fact be murder. Basil, a retired actor once famous for portraying none other than Sherlock Holmes on the big screen, finds himself unexpectedly tasked with unravelling the case. In a place no one can leave—and no one can reach—every guest and staff member becomes a suspect in a crime that grows more intricate and twisted by the minute.
