The atmosphere is required, cold and stinging. The characters spin in a bad way, the decor is devastated, the country in full political chaos, no confidence to grant the police are losing momentum, the relentless surveillance, threats and dished settling raining at all- will. In short, the plot takes us into the deep meanders and cafardeux of a spy novel. It is gray or pale and depressing.
The book was read on a cold winter evening. The symbiosis was complete. :-)
