"What did Garbitsch do with the information?" Boyd said.

"He passed it on," Brubitsch said. "Every week he would send a short-wave message to the homeland, in code. Some weeks he did not send the message."

"Why not?" Malone said.

"The radio did not work," Brubitsch said simply. "We received orders by short-wave, but sometimes we did not receive the orders. The radio was of very poor quality, and some weeks it refused to send any messages. On other weeks, it refused to receive any messages."

"Who was your contact in Russia?" Boyd said.

"A man named X," Brubitsch said. "Like in the formula."

"But what was his real name?" Malone said.

"Who knows?" Brubitsch said.

"What else did you do?" Boyd said.

"We met twice a week," Brubitsch said. "Sometimes in Garbitsch's home, sometimes in other places. Sometimes we had information. At other times, we were friends, having a social gathering."
