She stood silently, her gaze fixed on the protagonist in the photograph.
Upon closer inspection, the gaze of the woman in the black dress appeared somewhat gloomy.
"We compared her facial information with data from the security bureau, but found nothing," Huang Chen said.
"It could be a woman who has been dead for a long time," Yan Junze said.
In these photos, wherever there were passers-by in the background, the woman was there too, albeit sometimes very faintly, sometimes half obscured by someone else, revealing only half of her face.
Sometimes, her body was almost completely covered up, leaving only a glimpse of her black dress's hem.
Yan Junze took out his phone, opened Xia Ruolan's photo, and sure enough, in the background of the recreational villa in the photo, he also saw a woman in a black dress.
