"How can you be so hardened to this terror?" Osborne blinked away tears of dread. "When I stepped away from my quiet halls of study, it was to give my life in service to England and our queen, and to protect her from the great Catholic conspiracy… and the… the Spanish…" He swallowed. "The threats on her life from those who wish to turn us back to the terrible rule of Rome. Not this! I never foresaw that my soul would be placed at risk, until it was too late."

"Of course not," Mayhew sneered. If the common herd knew the real reason why England has established a network of spies the envy of all other nations, they would never rest in their beds. Do not fail me. Or the queen."

Osborne steadied himself. "You are right, Mayhew. I act like a child. I must be strong."

Mayhew clapped him on the shoulder with little affection. "Come, then. We have work to do."

They had only climbed a few steps when a tremendous crash resounded from the great oak door through which they had entered the Tower. Flashing a wide-eyed stare at Mayhew, Osborne took the steps two at a time. As they raced along the ringing corridors, Osborne asked breathlessly, "What is coming, Mayhew?"

"Best not to think of that now."

"What did they do to the guard? I knew him. Carter, a good man, with a wife and two girls."

"Stop asking foolish questions!"

The scream of one of the guards at the door below echoed through the Tower, cut short mercifully soon.

"Let nothing slow your step," Mayhew urged.

In the most secure area of the White Tower, they came to a heavy oak door studded with iron. The walls were thicker than a man's height. After Mayhew gave three sharp bursts of a coded knock, a hatch opened to reveal a pair of glowering eyes.

"Who goes?" came the voice from within.

"Mayhew and Osborne, your Lord Walsingham's men."
