The sky turns orange and the clouds turn yellow. Sunsets like this one have hung in galleries for centuries. A slight breeze rises – the lungs of the earth inhaling warmth, exhaling coolness. The breeze brings a faintly watery smell, even though the sun still warms the tops of trees. Beneath the trees, in cool green-black shadows, night begins, spreading a transitory stillness that will soon fill with the Invisibles – hyenas, leopards, lions – beginning their nightly rounds.
