Das fehlende Glied in der Kette

Poirot's unique personality and methods have become legendary. I wonder what inspired Christie to craft such a distinctive character.

The plot thickened at the start and then seemed to linger. I'm curious if the author aimed for a slower build or if it was just how the mystery unfolded.

The secluded country house really added to the suspense. I'm interested in whether Christie envisioned this setting from the beginning or chose it later.
