I joked about moving into no.13 on our street 'misfortune will surely follow', i said at our house warming. Within weeks our neighbour launched a campaign to oust us sending threatening letters and leaving bullets on the the doorstep (he has scared off four previous tenants, one a single mother with three small children), then we noticed the false wall ( still haven't plucked up the courage to investigate), maybe there is something in it after all.
