His eyes, sparked by his mounting excitement perhaps, had begun to play a startling trick. Flashes of color-rare, unnamable tints-were igniting in front of him, their origins the heart of the knot. The light caught his fingers as they worked. By it, his flesh became translucent. He could see his nerve endings, bright with newfound sensibility; the rods of his finger bones visible to the marrow Then, almost as suddenly as they flickered into being, the colors would die, leaving his eyes bewitched in darkness until once more they ignited.

His heart began to hammer in his ears. The knot, he sensed, was mere seconds from solution. The interwoven threads were positively springing apart. His fingers were the cord's playthings now, not the other way about. He opened loops to feed the other two knots through. He pulled, he pushed; all at the cord's behest.

And now colors came again, but this time his fingers were invisible, and instead he could see something glowing in the last few hitches of the knot. The form writhed like a fish in a net, growing bigger with every stitch he cast off. The hammer in his head doubled in tempo. The air around him had become almost glutinous, as if he were immersed in mud.

Someone whistled. He knew the signal should have carried some significance for him, but he couldn't recall what. There were too many distractions: the thickening air, his pounding head, the knot untying itself in his helpless hand while the figure at its center-sinuous, glittering-raged and swelled.

The whistle came again. This time its urgency shook him from his trance. He looked up. Brendan was already crossing the garden, with Catso trailing a few yards behind. Karney had a moment only to register their appearance before the knot initiated the final phase of its resolution. The last weave fell free, and the form at its heart leaped up toward Karney's face-growing at an exponential rate. He flung himself backward to avoid losing his head and the thing shot past him. Shocked, he stumbled in the tangle of brambles and fell in a bed of thorns. Above his head the foliage was shaking as if in a high wind. Leaves and small twigs showered down around him. He stared up into the branches to try and catch sight of the shape, but it was already out of sight.
