Cardona shook his head in response to Blake’s quiz.
“Any documents?”
“None of importance.”
“Suppose we go up there,” suggested the secret-service man.
“All right,” agreed Cardona. “Here’s something you’d like to look at before you go.”
He brought out the note which Philip Farmington had received from Double Z. The secret-service man examined it closely.
“You’re sure it is bona fide?” was his question.
Cardona produced other letters. For fully ten minutes, Terry Blake studied and compared the letters. He laid all aside except the note which had been found in the hand of Joel Caulkins — the note which warned the recipient he had but one week to live.
The secret-service man turned the note sideways, then upside down. He returned it to Cardona. The detective almost fancied that he saw a sudden gleam in Blake’s eyes. Before he could ask a question, the secret-service man had arisen.
“Let’s go,” he said brusquely.
