Yesterday, I wondered why it hadn't arrived so checked Amazon. They said it had arrived. It was either on the porch or beside the back door.
I check both locations. It was in neither. I therefore went outside in the rain and looked for it elsewhere in the garden.
It was leaning against the gate to the back garden, in a somewhat sodden cardboard box. It had been there over a week.
It's great that a book can be left outside in our neighbourhood and no-one steals it, but not so great that Amazon's delivery person thought that the gate to the back garden was the back door.
I think it's in quite good condition, given its experience of sleeping rough.
