L'attentat de Lancaster Gate (Grands détectives t. 31)

Anne Perry captures the era so vividly — I wonder what research or experiences influenced her portrayal of Lancaster Gate and its society.

The characters’ choices felt so weighty, especially given the social expectations of the time. How did readers interpret their struggles with loyalty and betrayal?

The setting feels so authentic, but I’m curious whether this was driven by strict research or creative choice to serve the plot better.
