A high-pitched sound, like steam escaping from a kettle whistles through the dark room. But nobody’s making tea. We both turn toward the source of the eerie noise.A weak stream of unearthly light seeps through the window near the corner of the room and pours onto the floor. Its consistency seems to lie somewhere between a liquid and a solid, like mercury, only blue. Out of the gleaming, wobbly puddle, a phosphorescent vapor rises up. The ghost we thought was Daniel materializes and looms over us for two seconds before he lunges and wraps his hands around Wyatt’s neck.
