“Yes?” questioned the Red Envoy, as Prokop hesitated. “He fell, you say?”

“He fell from the window,” continued Prokop, “but it is obvious that Berger had much to do with it. He must have done the job cleverly. Graham’s death is regarded as an accident.”

“I have read the newspapers,” remarked the man with the red mask. “The death of Jonathan Graham may prove useful. He controlled various interests that will deteriorate under other management.

“But regarding the matter of his private correspondence — “

He pauses, awaiting a reply from Prokop.

“Berger was not at to-night’s meeting,” said Prokop. “I did not expect him to be there. I suspected what had happened, when I learned of Graham’s death, last night. I sent a warning notice to Berger. After the meeting to-night, I mailed him his release.”

“That was the correct procedure,” replied the Red Envoy. “Cross his name from your list of agents.

“We can forget Berger, then. But the correspondence. Where is it?”

Prokop rose and went to a bookcase in the corner of the room. He took down a heavy volume of an encyclopedia, and opened the back of it.

The book was a secret box, from which Prokop produced a thick pile of papers. He brought the documents to the table, and laid them before the Red Envoy.
