Il quadro perduto di Van Gogh

The way characters are willing to risk everything for a Van Gogh masterpiece made me wonder about the real obsession behind art collecting. How do you think this obsession influences the story's tension?

The blend of art history and mystery added a rich layer to the story. I'm curious if the author’s background or interests shaped this setting.

The story seemed to take its time with details, which worked for me, but I wonder if others felt it slowed the momentum.
