I found a strange book in a hole in the ice of a frozen river

'Portkey to the Agit'

Agit...
This is a military term, that refers to a “small meeting place set up by secret organizations 
or operative within the operational area to carry out covert missions.”
And suddenly a stranger came out of somewhere, and I got a deja vu feeling about it.
He seemed to brush past me but then stopped and stared at me.

"You know, you look familiar." He said.

I couldn't say anything in response to that. 
Because I really didn't expect him to talk to me.
Then he continued speaking.

"Let me ask you a question."
