The Duke shuddered.

'Yes, it is true; that terrible thing I had not remembered. O God! if I could but find that accursed letter! At least, no one but myself need have known of the foul accusations; but now that the letter is lost——'

Wildly he began to search once more in the bureau, and Wilhelmine almost laughed when she saw him lift the packet of papers under which she had slipped Forstner's letter. With a cry the Duke turned to her.

'Thank God! I have found it! It lay here beneath this bundle. Wilhelmine, beloved, now none can read these blasphemies against you,' he cried.

'So you tell me to my face that yonder paper is a blasphemy against me, a foul accusation, and you will not let me clear myself!' she cried wildly.

'I swore to Forstner that I would never, in spoken or written word, divulge his communications—never give or voluntarily let another take his letters. Unless you can divine what you wish to know, there is no help.' He laughed harshly.

'Divine what is in that letter?' she said in a musing tone.

Suddenly a thought came to her. She remembered each word of that horrible letter. It was necessary his Highness should know she knew, yet imperative that her knowledge should appear to have been gained in his presence.

Wilhelmine had studied many books of magic and innumerable accounts of occult manifestations. She was half-dupe, half-charlatan, and indeed she possessed much magnetic power.

Now in Bavaria, some years before this scene at Ludwigsburg, there had been discovered an extraordinary peasant-girl gifted with rare faculties of clairvoyance, thought-reading, ecstatic trances, prophecies, and the rest. An account of her short twenty years of vision-tortured life had been published by the doctor of her village—a crank, and supposed wizard himself. This pamphlet Wilhelmine had read, as she read all books concerning mysterious manifestations. His Highness, however, would never look at anything treating of magic or witchcraft. He honestly disapproved of such things, and feared them; though, in contradiction, he was much attracted by his mistress's strange powers, which he affected to doubt, yet, in truth, he was terribly afraid at times.
