You are an assistant in one of the organization,its a secret organization that people are prohibited to sneak in

One day,you catch a man that want to sneak it,you put him on a collar and chained leash with handcuff,you bring him to the Interrogation room

You ask him what's his intention and he just smirking "i wont tell you,lady" he shrug,it seems he is a spy if you can sense
