The most trustworthy person she had about her was Helen Kottenner, the lady who had the charge of her little daughter, Princess Elizabeth, and to her she confided her desire that the crown might be secured, so as to prevent the Polish party from getting access to it. Helen herself has written down the history of these strange events, and of her own struggles of mind, at the risk she ran, and the doubt whether good would come of the intrigue; and there can be no doubt that, whether the Queen's conduct were praiseworthy or not, Helen dared a great peril for the sake purely of loyalty and fidelity. 'The Queen's commands', she says, 'sorely troubled me; for it was a dangerous venture for me and my little children, and I turned it over in my mind what I should do, for I had no one to take counsel of but God alone; and I thought if I did it not, and evil arose therefrom, I should be guilty before God and the world. So I consented to risk my life on this difficult undertaking; but desired to have someone to help me.' This was permitted; but the first person to whom the Lady of Kottenner confided her intention, a Croat, lost his color from alarm, looked like one half-dead, and went at once in search of his horse. The next thing that was heard of him was that he had had a bad fall from his horse, and had been obliged to return to Croatia, and the Queen remained much alarmed at her plans being known to one so faint-hearted. However, a more courageous confidant was afterwards found in a Hungarian gentleman, whose name has become illegible in Helen's old manuscript. The crown was in the vaults of the strong Castle of Plintenburg, also called Vissegrad, which stands upon a bend of the Danube, about twelve miles from the twin cities of Buda and Pesth. It was in a case within a chest, sealed with many seals, and since the King's death, it had been brought up by the nobles, who closely guarded both it and the Queen, into her apartments, and there examined and replaced in the chest. The next night, one of the Queen's ladies upset a wax taper, without being aware of it, and before the fire was discovered, and put out, the corner of the chest was singed, and a hole burnt in the blue velvet cushion that lay on the top. Upon this, the lords had caused the chest to be taken down again into the vault, and had fastened the doors with many locks and with seals. The Castle had further been put into the charge of Ladislas von Gara, the Queen's cousin, and Ban, or hereditary commander, of the border troops, and he had given it over to a Burggraf, or seneschal, who had placed his bed in the chamber where was the door leading to the vaults.
