Do Gnomes Conspire?

Does a gnome in the garden
keep fishing at night?
When the house is asleep
does he creep out of sight?
Is he holding a meet
to take over the world?
Or off to the neighbours
his lover to hold?
Can we ever be certain
just what is afoot?
When those ornaments
know we have upped and gone out?
So, in warning do you all
take care and take note?
And will you make certain
in concrete they’re set?
