Dwanaście prac Herkulesa

The stories are cleverly tied to mythological themes, but I'm curious whether this was planned from the start or developed later in the writing process.

His quirks and wit really come through, but I wonder if the Hercules theme influenced how Christie portrayed his character more than usual.

The labors format gives a fresh twist, but I’d love to hear if others felt it added a new layer of depth or just served as a fun framing device.
