Muller came back to the present with a start and said calmly,
"Fellner was a coward."

"Then you know more than you are telling me now?"

Muller nodded. "Yes, I do," he answered with a smile. "But I will
tell you more only when I have all the proofs in my own hand."

"And the criminal will escape us in the meantime."

"He has no idea that he is suspected."

"But - you'll promise to be sensible this time, Muller?"

"Yes. But you will pardon me my present reticence, even towards
you? I - I don't want to be thought a dreamer again."

"As in the Kniepp case?"

"As in the Kniepp case," repeated the little man with a strange
smile. "So please allow me to go about it in my own way. I will
tell you all you want to know to-morrow."

"To-morrow, then."

"May I now continue to unfold my theories?" Bauer nodded and
Muller continued: "The criminal wanted Fellner's blood, no matter
how."

"Even if it meant murder," said Bauer.
