Number Twelve Grimmauld Place

Noises creak from down the hall in the darkened corners
What could be lurking within the walls of Number Twelve Grimmauld Place?
The neighbours wonder who resides there in the suspicious home
Everyone wary until the building vanishes from sight and memory
Not a mouse was stirring, but there was a Kreature
And Number Twelve was much like a horror feature

Then one day the halls filled with joy and sorrow
The Order of the Phoenix lurked the rooms and halls
They plotted against evil, surrounded by Number Twelve's decay
Children and adults alike fought darkness in its depths
The neighbours never came to know what went on within
For the outside of Number Twelve Grimmauld Place would remain hidden
