About twenty ago, I heard a large crash on my roof. Now, I live in a fairly secluded area, so the wildlife doing things like this is not all that out of the ordinary. My house has been groaning for a while and I keep hearing voices coming from the fireplace. The chimney appears to be blocked by something. This may simply be in my head but I cannot for the life of me find the source of a distinct burnt minty smell. I am not sure if I should stick my head near the hearth to check what sort of devilish creature is haunting me tonight. What should I do?
