He watched the dancers, greedily catching the flash of their diamonds, gleaming tiaras, rings, necklaces, bracelets, each worth a king's ransom. Suddenly the idea flashed through his mind:

Bivens had taken from him, by fraud, his formula, destroyed his business and robbed him of all he possessed. The law gave him power to hold it. He, too, would appeal to the same power and take what belonged to him. No matter how, he would take it, and he would take it to-night.

Bivens had boasted that his favours in jewelry given in sheer wantonness of pride to rich guests would be worth twenty-five thousand dollars. His plan was instantly formed.

He turned quickly and began to search the house until he found the half-drunken servant arranging these packages under the direction of a secretary. These favours had been made for the occasion by a famous jeweller; a diamond pin of peculiar design, a gold death's head with diamond teeth and eyes surmounted by a butterfly and a caterpillar. The stones in each piece were worth a hundred dollars. They lay on a table in little open jewel boxes, fifty in a box, and each box contained five thousand dollars' worth of gold and precious stones.

The doctor inspected the boxes with exclamations of wonder and admiration.

The secretary who had lingered long over his champagne was busy trying to write the names of the guests on separate cards. The doctor bent low over the table for an instant, and when he left one of the jewel cases rested securely in his pocket.

He was amazed at his own skill and a thrill of fierce triumph filled his being as he realized that he had succeeded and that his little girl would go to Europe and complete her work. He spoke pleasantly to the secretary, and congratulating him on his good fortune in securing such a master, turned and strolled leisurely back to the ball room.

Not for a moment did he doubt the safety of his act. He was a chemist and knew the secrets of the laboratory. He would melt the gold into a single bar and sell the diamonds as he needed them. His only regret was that he could not have taken the full amount he had demanded of the little scoundrel.

He found Harriet and they started at once for home.

The dancers who were not staying for the second dinner, about to be announced at four o'clock, had begun to leave. Friends were helping the ladies to their cars and carriages, and other friends were labouring hopefully with those who were not yet convinced of the incapacity to take care of themselves.
