The moving boxes were finally, mostly, unpacked. Finnigan, grinning like a jack-o'-lantern, bounced on the balls of his feet as he surveyed the dust-sheeted hallway. He clapped his hands together, the sound echoing in the cavernous new home. "Right then," he announced to the empty space, his voice brimming with a lighthearted energy. "Adventure time!"

He started with the obvious: pressing every inch of wall in the downstairs rooms. He tapped, he knocked, he even ran his hands along the ornate molding, eyes sparkling with anticipation. The only yield was a sore palm.

Then, just as his enthusiasm was starting to wane, a section of the library wall clicked inward with a soft "thunk." A narrow, unlit doorway was revealed. Finnigan whooped, a sound of unadulterated delight. He practically skipped inside.
