Inside the room Marcy inspected her surroundings. The hotel and the room had been carefully selected, by Tom, to meet the criteria of his needs. Namel... an iron bedstead to which he could tie Marcy. Other than that it was pleasant enough. The décor was a bit flowery for Marcy’s taste but then she wouldn’t get see much of it anyway so what did it matter?

She had gotten what she had asked for, and that seemed to be all that was important to her right then.I spent the rest of that day out in the fields, working by myself..
