Layer Cake

The setting feels so authentic and immersive—I'm curious whether it was based on real places or purely fictional. Did the author draw from personal experience or research?

His choices kept me on edge, but I also wondered how much of his character was meant to evoke sympathy versus critique. How did others interpret his moral compass?

The layered revelations kept me guessing, but I wonder if this was planned from the start or evolved during the writing process. Did it affect how the suspense built?
