A wave of panic washed over her as she realized they would see her conversing with the waitress if the surveillance footage was retrieved.

Krista sat in terror at the thought of being exposed.

"I'm sorry, but our surveillance system has been down since this morning," apologized the hotel manager.

Krista breathed a sigh of relief. She subtly shook her head, signaling Karol not to proceed with the investigation.

Misinterpreting Krista's reaction, Karol reassured her, patting her shoulder, “Don't worry, Krista. Even if the video is down now, I can recover it. I'll unveil the culprit who did this to you."

With that, Karol retrieved her laptop and began typing away. Her fingers moved across the keyboard so swiftly that they astonished the onlookers.

"Miss Morris is truly remarkable! The pride of the Morris family."

"The Morris family has a long history of considerable wealth. Of course, they would have plenty of educational resources."

In no time, the surveillance video materialized on Karol's laptop screen. The spectators were in awe, but the blood drained from Krista's face.

Karol meticulously traced the waitress's movements since the morning.

She could be seen fetching water and the fruit plates and then delivering them to each dressing room.

She handed a glass of water to Effie, and a moment later, the waitress entered Effie's room again and delivered the fruit plate.

When the waitress turned to leave, Effie swapped her glass with another on the tray.

Observing the detail, Karol narrowed her eyes and glanced at Effie.

“Why the switch? What's the story behind exchanging your water glass?"

Effie shot Karol a look, treating her like she was an idiot. “Did you notice I finished the water? Obviously, I swapped the empty glass for a full one."

Her explanation made sense.

The waitress observed the whole thing, her eyes reflecting a shift in emotion.

Thinking she had an empty glass on her tray at that time, she filled it before heading to Krista's room.

It turned out that the glass was Effie's and was laced with the drug.

Leaving Effie's room, the waitress went to Krista's, placing a fruit plate and water glass on her table. After a brief chat, she was gone.

That marked the end of the waitress's trail.

Effie taunted, "Are you still doubting me? I don't even know this waitress."

“The waitress served the fruit plates and water glasses to others simultaneously. But she gave you the fruit plate after the water. She entered your room twice. Why?" Karol kept staring at Effie sternly.
