"That is too bad," said Katrina. "You see, when I knew him he was only a chemical captain. And when he deserted me I didn't really care much. But when the Royal Captain Grauble asked me to meet a Karl von Armstadt of the Chemical Staff, at first I could not believe that it was the same man I had known, but I made inquiries and learned of your rapid rise and traced it back and I thought you really were my old Karl. And when I saw you, you seemed to be he, but when I looked again I knew that you were another and I was so disappointed and angry that I lost control of my temper. I am sorry I made a scene, and that official was so stupid--as if I would not know one man from another! How I should like to tell him that I knew more than his stupid records."

"But that is not best," I said; "your former lover is dead and there are grave reasons why that death should not be investigated further--" The argument was becoming a little difficult for me and I hastened to add: "Since you were so discourteously treated by the official, I feel that I owe you some little token of reparation."

I now drew out the necklace and held it out to the girl.

Her black eyes gleamed with triumph at the sight of the bauble. Greedily she grasped it and held it up between her and the light, turning it about and watching the red rays gleaming through the stones. "And now," she gloated, "that faded Elsa will cease to lord it over me--and to think that another Karl Armstadt has brought me this--why that stingy fellow would never have bought me a blue-stone ring, if he had been made the Emperor's Minister."

Katrina now rose and preened before her mirror. "Won't you place it round my neck?" she asked, holding out the necklace.

Nor daring to give offence, I took the chain of rubies and attempted to fasten it round her neck. The mechanism of the fastening was strange to me and I was some time in getting the thing adjusted. Just as I had succeeded in hooking the clasp, I heard a curdled oath and the neglected Holknecht hurled himself upon us, striking me on the temple with one fist and clutching at the throat of the girl with the other hand.

The blow sent me reeling to the floor but in another instant I was up and had collared him and dragged him away.

"Damn you both," he whimpered; "where do I come in?"

"Put him out," said Katrina, with a glance of disdain at the cowering man.

"I will go," snarled Holknecht, and he wrenched from my grasp and darted toward the door. I followed, but he was fairly running down the passage and pursuit was too undignified a thing to consider.
