His job wasn't over. It never would be—until disease or old age or the dagger of some local enemy ended it. There was so much to do, and only a few decades to do it in; compasses and steam engines and microscopes and the writ of habeas corpus.
He'd teetered along for over a year and a half, grabbing a little power here, placating a possible enemy there, keeping far enough out of the bad graces of the various churches, starting some little art such as spinning of sheet copper. Not bad for Mouse Padway! Maybe he could keep it up for years.
And if he couldn't—if enough people finally got fed up with the innovations of Mysterious Martinus—well, there was a semaphore telegraph system running the length and breadth of Italy, some day to be replaced by a true electric telegraph, if he could find time for the necessary experiments. There was a public letter post about to be set up. There were presses in Florence and Rome and Naples pouring out books and pamphlets and newspapers. Whatever happened to him, these things would go on. They'd become too well rooted to be destroyed by accident.
History had, without question, been changed.
Darkness would not fall.
