They arrived early. There weren't many cars in the school parking lot.
After parking the police car, Dean got out and called to Nellie, who was heading towards the school office building, "No rush. Let's wait here for a bit; we might get an unexpected lead."
Nellie was initially puzzled, then it dawned on her. "Detective Dean, do you mean the owner of the grey sedan might be a member of the school staff?"
Dean nodded. "Or a student."
Toddy, the female teacher, led a very regular and respectable life. The people she knew were either students, their parents, or other teachers at the school. So, waiting here might prove fruitful.
The two of them didn't just stand foolishly by the police car; instead, they moved to an inconspicuous corner that offered a good view of the parking spots.
As class time approached, fewer cars entered from outside.
"Looks like we waited for nothing," Nellie said, a little disappointed.
