A light rustling on the tapestry door interrupted him; and he turned anxiously toward this door, which led directly to the chamber of the king, and through which he alone could enter.  It was indeed Frederick.  He entered the room of his private secretary with a bright, gay smile.

“I have come unexpectedly,” said the king.  His clear, piercing glance instantly remarked the cloud which lowered upon the brow of Fredersdorf.  “But what will you have?  The King and Fate, as Deus ex machina, appear without warning and confuse the calculations of insignificant mortals.”

“I have made no calculations, sire,” said Fredersdorf, confused; “and the presence of my king can never disturb my peace.”

“So much the better,” said Frederick, smiling.  “Well, I have made my calculations, and you, Fredersdorf, have an important part to play.  We have a great work on hand, and if you have set your heart upon being at liberty this evening, I regret it; the hope is a vain one.  This evening you are the prisoner of your king.”

The king said this with so grave, so peculiar, and at the same time so kindly an expression, that Fredersdorf was involuntarily touched and softened, and he pressed his lips warmly upon the hand which Frederick held out to him.

“We must work diligently,” said the king.  “The time of idleness is past, and also the time consecrated to the Muses.  Soon I will lay my flute in its case, and draw my sword from its scabbard.  It appears that my godmother, Maria Theresa, thinks it unseemly for a King of Prussia to pass his days elsewhere than in a tented field, or to hear other music than the sound of trumpet or the thunder of cannon calling loudly to battle.  Well, if Austria will have war, she shall have it promptly.  Never will Prussia yield to her imperious conditions, and never will the house of Hohenzollern subject herself to the house of Hapsburg.  My godmother, the empress, can never forget that the Prince-Elector of Brandenburg once, at the table, held a wash-basin for the emperor.  For this reason she always regards us as cavaliere servente to the house of Hapsburg.  Now, by the help of England, Saxony, and Russia, she hopes to bring us under the old yoke.  But she shall not succeed.  She has made an alliance with England, Russia, and Saxony.  I have united with France and Bavaria, for the protection of Charles the Seventh.  This, you see, Fredersdorf, is war.  Our life of fantasy and dreaming is over.  I have given you a little dish of politics,” said the king, after a pause.  “I wish to show you that I have need of you, and that we have much to do.  We must arrange my private accounts, we have many letters to write; and then we must select and prepare the rich presents to be given to the Princess Ulrica on her marriage.  Fredersdorf, we cannot afford to be idle.”

“I shall be ready at all times to obey the commands of my king.  I will work the entire night; but I pray your majesty to grant me a few hours this evening—­I have most important business, which cannot be postponed.”
