Grimm's School for the Erratically Gifted: Chapter 7
After a suitable mourning period for his lost bent-key,[^fn:1] Edmund refocused his efforts.
He needed a new bent-key. A better one. One that could easily circumvent the lock on Tunansia’s chest, and even more besides. To that end, Edmund resolved to research everything he could, from engineering and metallurgy to the newest locksmithing theories. Once he was well-educated, there wouldn’t be a lock in the world that could keep him out.
By lunchtime that day, he paused to make a new bent-key from a hat-pin he had found on the hallway floor. Even though it was lighter and flimsier than his old broken bent-key, it made him feel better to have one in his pocket.
For two more days he spent his time in the Grimm’s library, pulling books and papers on locksmithing down from the dark-wood shelves. It was a long and arduous process, as most of the books he could find were devoted to theoretical lockery, as opposed to the practical application of the physics and mechanics involved.
