“Who is it?” demanded Klein.

The detective made a grimace. He signaled his superior not to interrupt. Fumbling on the table before him, he found a pad and pencil.

“The Lukens murderer?” he questioned. “You’ll have him for me? With the evidence?”

There was a pause as the detective listened intently. Then his voice spoke in more startled tones.

“The Blake case? You’ll have that, too? The murderer… Oh, you’ll clear it, you say… What’s that?… Yes, yes—”

He began to write hurriedly. Klein leaned over, but could not decipher his shaky scrawl. Occasionally Cardona exclaimed the word “Yes.” Then, finished with his notes, he slumped into a chair. Klein grabbed the phone.

“Hello!” he demanded.

The receiver clicked at the other end.

“Who was it?” exclaimed the inspector.

“The Shadow!” replied Cardona.
