Chapter four: a lot of things said Mr. Adams

 Eric Adams also known as the man in the blue bikini, whose parents worked as subway builders/underground builders when he was young. In Eric's teens for a lot of years ago, they became sick pensioners. So, his newly married cousin Bob and his wife Theresia came later on same day on a visit. At 9:09 am next morning, Eric Adams got a mail in the letter box in the door on the fifth floor, there it stood:

Eric John Adams

The Machine Street 121

Five stairs up in the apartment/flat to left with a big balcony

Philadelphia, Green Town

And in the mail it stood that he would work on the day before the new years eve.
