If you would, coax your mind back to a time when you believed ducking your head beneath the covers was ample defense against the bogeyman. Do you remember, in the haze of half-sleep, seeing something or someone in your room that didn’t belong? As you breathlessly flicked on the light, you were relieved to find it was only a chair lopsided with laundry, or a vacuum propped against the doorframe. That faint halo of light, surrounding this once sinister and now innocuous object, that is the penumbra – that permeable border between light and dark. This is the space where Enigma lives.
