In a private terminal at the Port of Boston there is a houseboat. This houseboat has been anchored there, permanently, for at least fifty years. The eccentric owner has maintained all fees and taxes and is in good standing with the Port Authority. Still, even if the owner wasn’t financially responsible, no one would ask them to depart. Despite the owner’s friendly, hospitable, if odd nature, there is a persistent air of unease around the boat and the area of the Port surrounding.
