Mass Murder

"Inspector, it's already 11:00 PM, but her mother hasn't returned home yet." Standing before the Inspector was Swetha and her grandpa. They had an expression of worry as they looked at the Inspector, wishing the other party could solve it.

"Ugh," The Inspector grunted as he removed his feet from the table, buttoning his shirt that he had loosened to relax during the night. He then took his seat as he spoke in his usual gritty tone, "Where was she last seen?"

"She and my granddaughter visited the Mysore Palace today. But, somewhere in that area, they had been separated." The grandpa said with a frown as he pointed at Swetha, "And, someone dropped her at our house just earlier."

He then handed him the visiting card Re'Kha had given Swetha, "This is the visiting card of the lady that dropped her."

"Anything else?" The Inspector frowned as he looked at Swetha, "Did your mother tell you to meet at someplace if you were to get lost?"
