Aroused by the shots the guards were gathering at the point of the sudden alarm. The ground was being examined closely, guards walked back and forth beating about in the underbrush. In a moment the bomb was discovered, dropped where Dollings had left it in his flight.
The discovery of the blood spattered bomb and the attempt upon the factory was reported at once. A message went to Washington. From Washington a message went to Harrison Grant at the Criminology Club. And Harrison Grant having received the message lost no time in getting to Hopewell. The Secret Service needed him there.
When Dixie Mason arrived in Richmond the day after the attempt on Hopewell, she went directly to the hotel at which Madam Stephan and Von Lertz were registered. It was the hottest part of the day and the hotel lobby was deserted. Dixie asked for the proprietor. Showing him her Secret Service Commission she took him into her confidence to the extent of making him understand that she wanted a room next to the one occupied by Madam Stephan, and that she did not wish her name to appear on the register.
"It can be arranged, very easily," he assured her.
Dixie was gracious in her thanks. "But you had better make a card entry of my name so that in case I am forced to come in contact with either Von Lertz or Stephan, I can have an alibi."
"The clerk will take the blame," smiled the proprietor.
Very shortly Dixie was installed in a room next to Madam Stephan's. A door connecting the rooms was locked and bolted—on Madam Stephan's side, but this fact was of no concern to Dixie. She had brought out the Panelphone and examined its delicate mechanism; attached the batteries which gave it the telephonic electrical connection necessary to the transmission of sound, and then by means of a vacuum cup had fastened it to the door. By this device each sound within the next room would be intensified sufficiently for her to hear every word of any conversation carried on.
She placed the receiver at her ear. The low murmur of voices which she had heard a moment before now was magnified so that each sound reached her with a clarity allowing no chance for mistakes.
Madam Stephan was speaking. Her usually well-modulated voice carried an acid quality, an angry sarcasm that conveyed a deep displeasure.
"Your little plan of taking my place seems to have failed, Baroness. Your endeavor to worm your way into Von Papen's favor through Von Lertz has not met with the success you aspired to." There was a sudden rustle of a newspaper being straightened out, then the caustic tones of the Madame cut the silence once more. "Spy Fails in Attempt Against Guncotton Plant," she read. "Believed to have been injured by guard! A very good start, Baroness, for your operations in America. Three months in Hopewell and this is what you have accomplished!"
