Rising from the grassy field like gigantic broken teeth, the site held an air of eerie foreboding. It was no wonder, Griffin thought, that Professor Moriarty and Nigel had chosen such a place to hide their new base of operations.

Quickly!” Using his walking stick, Griffin hurried forward as fast as he could, watching how the last beam of light traveled along a stone standing directly across from where it set.
