“Vous êtes Français, Monsieur?” said the King, addressing him in French, of which language my father understood only a few words.
“Je suis Français, votre Majesté,” replied Monsieur Maurice.
“Comment!” said the King, still in French. “Our person, then, is not unknown to you?”
“I have repeatedly enjoyed the honour of being in your Majesty's presence,” replied Monsieur Maurice, respectfully.
Being then asked where, and on what occasion, my father understood him to say that he had seen his Majesty at Erfurt during the great meeting of the Sovereigns under Napoleon the First, and again at the Congress of Vienna; and also that he had, at that time, occupied some important office, such, perhaps, as military secretary, about the person of the Emperor. The King then proceeded to question him on matters relating to his imprisonment and his previous history, to all of which Monsieur Maurice seemed to reply at some length, and with great earnestness of manner. Of these explanations, however, my father's imperfect knowledge of the language enabled him to catch only a few words here and there.
Presently, in the midst of a somewhat lengthy statement, Monsieur Maurice pronounced the name of Baron von Bulow. Hereupon the King checked him by a gesture; desired all present to withdraw; caused the door to be closed; and carried on the rest of the examination in private. By and by, after the lapse of nearly three quarters of an hour, my father was recalled, and an officer in waiting was despatched to Monsieur Maurice's rooms to fetch what was left of the bottle of Seltzer-water, which Monsieur Maurice had himself locked up in the sideboard the night before.
The King then asked if there was any scientific man in Brühl capable of analysing the liquid; to which my father replied that no such person could be found nearer than Cologne or Bonn. Hereupon a dog was brought in from the stables, and, having been made to swallow about a quarter of a pint of the Seltzer-water, was presently taken with convulsions, and died on the spot.
The King then desired that the body of the dog, and all that yet remained in the bottle should be despatched to the Professor of Chemistry at Bonn, for immediate examination.
This done, he turned to Monsieur Maurice, and said in German, so that all present might hear and understand:—
“Monsieur, so far as we have the present means of judging, you have suffered an illegal and unjust imprisonment, and a base attempt has been made upon your life. You appear to be the victim of a foul conspiracy, and it will be our first care to sift that conspiracy to the bottom. In the meanwhile, we restore your liberty, requiring only your parole d'honneur, as a gentleman, a soldier, and a Frenchman, to present yourself at Berlin, if summoned, at any time required within the next three months.”
