Theo already knew about the email that had been sent to their doorstep so getting to the house, Alice noticed the envelope on the email box right outside the house though it was dark already, she could still see the white paper in the email box due to the street light that was set right at the side of her gate.
Alice got out of the car and went back to the gate, she dragged the letter out from the email box through the little hole in it. She examined it for some minutes but couldn't understand the name used as the sender's ID.
"Theo come check this out" Alice moved away from the gate into the house. "A letter has been sent but the Sender ID seems complicated or let's say hidden" Alice called on Theo's attention as he was done parking the car. She had announced to Theo about the letter as she walked closer to where he stood.
