“Because I am reasonably certain that the Director of Police will see him early to-morrow morning, and I want to get the first copy of the analysis myself.”

With that the Princess ran away and presently reappeared with her wraps on. The two drove to the shop of Herr Feltz in the Graubenstrasse, and were told that the chemist could not be seen in any circumstances. He had left orders that he was not to be disturbed.

“Disobey those orders and take in my card,” said the Princess.

A glance at the card dissolved the man’s doubts, and he departed to seek his master.

“He is working at the analysis now, I’ll warrant,” whispered the Princess to her companion. In a short time Herr Feltz himself appeared. He greeted the Princess with most deferential respect, but seemed astonished to find in her company the young woman who had called on him a few hours previously with the Director of the Police.

“I wanted to ask you,” said Jennie, “to finish your analysis somewhat earlier than four o’clock to-morrow. I suppose it can be done?”

The man of science smiled and looked at her for a moment, but did not reply. “You will oblige my friend, I hope,” said the Princess.

“I should be delighted to oblige any friend of your Highness,” answered the chemist slowly, “but, unfortunately, in this instance I have orders from an authority not to be disputed.”

“What orders?” demanded the Princess.

“I promised the analysis at four o’clock to-morrow, and at that hour it will be ready for the young lady. I am ordered not to show the analysis to anyone before that time.”
