"I don't know what you're talking about. I'm telling the truth. Why are you insisting that I'm lying?" The woman was shocked, wondering what exactly did she see in the photo.
"Captain, the staff of our hotel only clean up when the guests go out, and the cleaning time for this room is 5:30 p.m. which is fifteen minutes before Yulia and this lady come back. The cleaner will squeeze out a toilet cleanser in the toilet. Since this lady has not been to the toilet, why did the cleanser in the toilet already disappeared?" Rory did not keep her guessing and explained to the captain seriously.
The police chief glanced at Rory and turned to the woman. "Why don't we go take a look at the irrigation system? It doesn't matter if we open the sewer. Let's see what's been washed away."
If they do that, the entire hotel would be suspending their business for quite a while. But this was far better than being accused of poisoning a guest.
