I was normal. Or at least, that’s what I had always believed. I had a normal family, with a normal father and mother, who had normal jobs, and a little sister with whom I had a perfectly normal fight. But that all changed. My great-greatgrandfather had left us a large mansion as an inheritance and my parents had no time to organise the move. All that was not even half normal, neither the mystery hidden in that house on the top of the hill.
