So the Boy has a cough. A bad cough. They called from school to say he wasn't well and could I fetch him. I did.
On the way home we had to stop off at the house we rent out to let in some workmen (boiler).
Car in the drive indicated someone at home.
We rang the bell. Nothing

We hammered on the door. Nothing

So I let us all in with my keys.
The Boy said "There must be someone in" and shot off upstairs.
He came back. "Yes, he is lying on top of a girl and sort of jumping and she is screaming.I told him to stop, but he didn't hear me"

We fled!
