"I was going to make a full-sized gun. We have a disappearing gun platform built in the swamps at the juncture of the Potomac and Piscataway Creek. The gun was to be mounted there and we would shell Washington and institute a reign of terror. It would be a signal for uprisings all over the country."
"Is there a black lamp at that gun platform?"
"Yes. The black lamp will kill both the flash and the report."
"Where did you get the formula for radite?"
"We got it from one of Dr. Bird's assistants. His name—"
s he spoke the last few sentences, Karuska's voice had steadily risen almost to a shriek. As he endeavored to give the name of the doctor's treacherous helper his voice changed to an unintelligible screech and then died away into silence. Major Martin stepped forward and bent over the prone figure. Hurriedly he tore away the electrical connections and placed a stethoscope over the Russian's heart. He listened for a moment and then straightened up, his face pale.
"I hope that the information you obtained is worth a life, Dr. Bird," he said, his voice trembling slightly, "because it has cost one."
"It may easily save thousands of lives. I thank you, Major, and I will see that no blame attaches to you for your actions. I only wish that he had lived long enough to tell me the name of my assistant who has sold me to Saranoff. However, we'll get that information in other ways. Carnes, telephone Lawson at Atlanta to slam O'Grady into a cell pending investigation while I get Camp Meade on the wire and order up a couple of tanks. We are going to attack that gun emplacement at daybreak."
