In Soul Music, Susan explores multiple times the area surrounding Death's cottage. Everything is how we are used to know it, with the predominance of black and the constant feeling that things are odd because, well, Death has no real experience of things and thus can never get anything really right.
But in Soul Music Susan finds, behind the usual garden area, a "real" field of corn with everything perfectly in place, colours included.
Is this a nod to Death experience as Bill Door in Reaper Man? Do we see Death creating them, in any of the books?
