CHAPTER XII. TWO PRISONERS

Herman Spier had made his escape with the letter. He ran through tortuous byways of the old city, under arches into courtyards, out again by doorway set in walls, twisted, doubled like a rabbit. And all this with no pursuit, save the pricking one of terror.

He eyed his creature with cold anger. “It is a marvel,” he sneered, “that such flight as yours has not brought the police in a pack at your heels.”

“I had the letter,” Herman replied sulkily. “It was necessary to save it.”

“You were to see where Niburg took the substitute.”

But here Herman was the one to sneer. “Niburg!” he said. “You know well enough that he will take no substitute to-night, or any night, You strike hard, my friend.”
