A Slight Mistake

"I believe you are lying", the lieutenant said.
The soothsayer smiled.
"I am Gemini. We are expected to be creative."

Wearing his hair neatly parted, 1/3 towards the right of the head, he could be mistaken for an accountant, rather than an astrologer.

"So, where have you been?", the policeman asked.
"Let me serve some tea, first."
The man left the room.
When he returned, the lieutenant jumped up.
"Wait here!"

He darted away.
Five minutes later he returned, leading in handcuffs an exact double of the astrologer.
The man smiled:
"Well, Gemini is a bit vague. Let's say TWIN."
