"That explains it," Carver remarked. "I couldn't account for their leaving you behind."
Peter Gross lapsed into silence again.
"Did you get anything else from him, any real evidence?" Carver suggested presently.
The resident roused himself with an effort.
"A great deal. Even more than I like to believe."
"He turned state's evidence?"
"You might call it that."
"You got enough to clear up this mess?"
"No," Peter Gross replied slowly. "I would not say that. What he told me deals largely with past events, things that happened before I came here. It is the present with which we have to deal."
"I'm a little curious," Carver confessed.
