Mejor el diablo (john rebus, 21)

Rebus stories feel so rooted in Edinburgh's atmosphere, but I wonder how Rankin keeps the suspense fresh while developing the character over time.

His decisions often blur the line between right and wrong, which made me question what I would do in his place. How do others interpret his moral compass?

The city feels almost alive and integral to the story. I'm curious whether the author based it on personal experience or extensive research.
