Does something lie beneath?

Lake of Flies

The lake looks still.
The lake has only gentle ripples.
The lake hosts clouds of swarming flies.
The flies are unaware
The lake emits an air of menace.
The lake has great, dark conifer-reflection teeth.
The lake wants to drag me in and drown me.
The lake-spirit is not friendly.
The lake-spirit is malign.
The lake-edge is slippery –
All the better to grab a sliding limb
And pull it in;
I pull back.
The lake-water is black.
The lake may be deep or shallow.
The lake is a mirror of obsidian.
The lake stares back.
The lake dares you to stay too long.
The flies do not care.
The flies hum and hypnotise.
They bite and breed,
They breed and feed.
The lake holds onto secrets.
The flies suggest you seek them out.

The lake seems calm.
The lake is.
