Alien pods!

They appear overnight in fields all over the UK, rows and stacks of them, incubating according to the Dormouse, throughout the summer and Autumn.

Then! ..... in late winter  they disappear just as quickly. The aliens have hatched and integrated themselves into the community.They think we don't know who they are .... but we do!

It'll be interesting to see how many "hits" a title with aliens in it gets compared with, "butter making at home".
