Did you realize there were so many weapons to fight ghosts with? No, me either!!!!
The "Fittes Manual" advises against its use of this indoors, except under controlled conditions. page 47.
Discuss what this weapon is and what are the consequences of Lucy using this weapon?
Name one other type of ghost fighting weapon you found in "The Screaming Staircase" and how you think the weapon is used and how it would protect you when a ghost appeared.
