They've been preparing an escape for a long time. Being afraid not to give themselves away as much longer as possible, it became almost a habit, from the very day when the decision was made. The details were worked through secretly, but everyone understood exactly what the next step would be. Time went by and some aspects and nuances became worked out before automation. Planning took place on certain days, when it was most convenient. And those moment, the most convenient case, was coming closer and closer. To get out, disappeared, to dissolve, so that nobody would notice anything, at least for a while. That day, that very hour, that minute, the main move, like on a chessboard, it turned out to be as easy as pressing a key on a keyboard.
