This guy must have known exactly where Rosemary's grandparents were headed next and had someone set up a stall there in advance.
Perhaps all the dangers her grandparents encountered on the way were artificially created.
After ending the call, several servants gazed at Rosemary with anticipation. It took them a while before they finally said,
"Ms. Rose, only a select few knew the travel route your grandparents were taking."
"Who exactly?" Rosemary was slightly surprised. She didn't expect these servants to be in the know.
"Just family members and friends of your grandparents."
"Because of their extensive contacts, they had to deal with all sorts of obligations every time they went to a new place, which would keep them from fully enjoying their trip."
"I once heard your grandmother voicing such concerns to a few close friends, saying she didn't want to deal with too many social obligations."
"Tell me their names."
