One Access Card, One Big Secret
Yvonne Larson, my housekeeper, has always been punctual, but she ends up being late today.
"I'm so sorry, Mr. Carter. Dinner's not ready yet. I hope you won't mind. I had no choice. I waited for over half an hour, but no one got the door for me. I even called Mrs. Carter a few times, but she didn't take my calls. That's why I ended up running late."
Halfway through changing into my house slippers, I pause and frown.
"Yvonne, didn't Susanna give you the access card to the apartment?"
Yvonne looks confused. "The access card? Mrs. Carter never gave me any card."
"Never?"
"That's right," Yvonne confirms timidly while wiping the sweat off her brow. "For the past month, I've always had to call Mrs. Carter and ask her to open the door for me. She wasn't picking up her phone today, so I had to wait outside…"
That's strange.
I've checked the logs before. The access card has been used multiple times throughout the past month.
