Even if Bella Scott were more obtuse, she would know that someone was following her, not to mention that she was an expert in this field.
At first, she didn't care much about it, after all, she was at the headquarters, and no thief would be foolish enough to attack her on her own turf.
But after a while, she realized something was amiss.
Because the person following her was very clumsy, judging by the footsteps, it didn't sound like an adult's footsteps. Listening to the lightness of the sound, it was obviously a child stalking her.
She remembered that Clarky and Clara had mentioned that Edward Anderson's adopted child had also come to the headquarters.
Maybe it was Edward Anderson's doing, with the child persistently bothering her?
She slowed down her pace and looked back, only to see Jessica Scott, who was following her, immediately hide to the side.
