Disclaimer: I have an over-active imagination and am very paranoid 
Over the last two days, DH and I have killed around 40 bluebottle flies. I killed 12 in the space of ten minutes this afternoon. We were worried that we had an infestation but we've poked around in the loft/cellar and nothing. All our windows are closed so they're not getting in that way.
We just went outside to investigate around by the bins and DH pointed out that in nextdoor neighbour's back window there were seven of these flies.
He is a bit of an oddball tbh. Since his girlfriend left he's been doing weird stuff like not going to work but wearing a suit and coming and going at weird hours. He never seems to have visitors and he clips his hedge with nail scissors.
You know what I'm thinking. DH has suggested it too but he is more of a fantasist than even I am
AIBU in thinking there might be a dead body nextdoor?
