"Yes, sir."

The servant bowed and left the room. The Black Star took paper out of a drawer, and a box of rubber stamps, and began composing a letter that was to cause the chief of police, the sheriff and Roger Verbeck much chagrin before morning.

To those poor fools whom it most concerns:

I was amused at the manner in which you guarded the little cottage so well. That fake headquarters was placed there in order to have you send all officers to the National Trust Building. I understand it fooled even Roger Verbeck. You may place all the blame on the sheriff, since he responded so well to my decoy. While you guard the National Trust, I shall be looting the First National of the shipment of currency it received to-day. It is the first blow in my campaign. And when you learn that I am looting it, and rush there, I shall——But you will know what by the time you read this note.

The Black Star put the folded note into an envelope, and addressed it to the chief of police. Then he composed another to be mailed to a prominent newspaper.

I, the Black Star, begin my campaign to-night. Three nights from now, I and my men shall steal certain jewels and art objects that are famous. You may guess what they are, and where. Guard all jewels and objects of art in the city, if you wish, but that will not prevent us from getting them. *****

The Black Star put the letter into an envelope, addressed it, and then put both letters into one of his pockets. He glanced at his watch, and took off his robe, but retained the mask. He donned a heavy ulster, and rang for the servant again.

"Tell the mechanic to be ready in ten minutes," he said.

"Yes, sir."

"After I have left the house, throw on the protecting current, and do not turn it off unless you get the proper signal."

"I understand, sir."
