I started to feel uneasy. But before I could say anything, something unexpected happened.

My dog, Koko, who had been lying calmly by our table, suddenly jumped up, charged toward the woman, and bit her on the arm. The woman screamed in pain and fear, trying to fight the dog off and begging us to remove him. Guests ran over, including my bride.

— What’s going on?! — she shouted.
— Koko bit one of your relatives! — someone said.
— Who? What relative?

I pointed at the woman in green. My wife stepped closer, looked at her, and whispered in my ear:
— I’ve never seen this woman before. She’s not one of our guests.

Panic broke out. Who was she? Why was she there? Why did Koko react like that? I saw my dog barking and shaking, as if trying to protect us.
