The Laughing Cavalier by Emma Orczy

What a commotion when dawn breaks at last; it comes grey, dull, leaden, scarce lighter than the night, the haze more dense, the frost more biting. But it does break at last after that interminable night of excitement and sleeplessness and preparations for the morrow.

Jan has never closed an eye, he has scarcely rested even, pacing up and down, in and out of those gargantuan beams, with the molens and its secrets towering above his head. Nor I imagine did those noble lords and mynheers up there sleep much during this night; but they were tired and lay like logs upon straw paillasses, living over again the past few hours, the carrying of heavy iron boxes one by one from the molens to the wooden bridge, the unloading there, the unpacking in the darkness, and the disposal of the death-dealing powder, black and evil smelling, which will put an end with its one mighty crash--to tyranny and the Stadtholder's life.
