Secrets in the Safe

"What?" In the office, Zhao Yu roared. "A safe... Again?"

Wu Xiumin replied, "Yes, Zhang Jingru rented a safe at the Evergreen Development Bank in Longjiang City. The date was October 21! She paid for only one month, and as the bank allowed one month for late payment, she received the payment reminder last month!"

Zhao Yu frowned as he said, "October 21 was the week before Zhang Jingru was killed! Did she keep anything important in the safe?"

"Longjiang is the nearest prefecture-level city to the Golden City!" Zeng Ke analyzed aloud. "No bank in the entire Golden City rents out safes, so that explains why Zhang Jingru chose to go to Longjiang!"

Wu Xiumin then said, "According to our records, Zhang Jingru was absent from work on October 21. I'll ask her company the reason why."

"Wait a minute!" Zhao Yu said. "Wu, ask the Longjiang police to find out what was in the safe first! We need to know what Zhang Jingru put in the safe as soon as possible."
