Unseen Surveillance

Boss John: What happened? Explain it to me. Is your health okay? You seemed ill the day before yesterday and left early.

Maria: No, Boss, it's not about my health. I'm perfectly fine.

Boss: Then, what happened?

Maria: She explains everything that happened at night.

Boss: What do you mean? Any idea? Did you both get drunk last night?

Maria: Not at all, boss. You know I don't drink, and Saim doesn't either.

Boss: Any other clues? Have you asked Saim? Are you suspicious of him?

Maria: No, boss, not at all. He was fast asleep before I woke up. When I did wake him, he got angry and left without listening to my explanation.

Boss: So, what do you think happened?

Maria: I searched my house and found a knife and an empty spray bottle at the door, and the door lock was broken.

Boss: This is terrible! Who did this? It means someone came to hurt you, not steal anything?

Maria: No, boss, I don't think someone came to steal anything since everything is still here.
