Slythurst tried to pull me up roughly by the arm, but I twisted away from him, curling my body around the package lest he try to wrench it from me.

"You will explain yourself this time, Bruno," he said, anger replacing his usual cold sarcasm as I struggled against his grip and he tried to reach for the package. It was too much of a coincidence that he should be awake and dressed at this hour of the night; he must have been watching Norris's room. "What is it you have taken from that room? I must see it. I demand you hand it over to me." There was a hectic urgency in his voice and I saw genuine alarm in his eyes as he looked at the bundle in my hand. Could it be that he knew the importance of what I carried?

"Demand all you like," I gasped, lashing out with my bandaged hand, "but I cannot give this to you."

"I am a senior Fellow of this college," Slythurst spluttered, trying to keep his dignity, "and you must acknowledge my authority here. If you have taken something of value from a student's room, it must be shown to the rector." His tone was shrill with panic. Again he tried to snatch it; again I jerked away from him. I saw that he was determined to have it, and knew that it must not fall into the hands of the rector; both Slythurst and Underhill, I thought, were quite capable of destroying any evidence they thought might make things difficult for the college, and my discovery in Norris's room would be the end of Underhill if it was made public. Slythurst studied me for a moment, his mouth set in a grim line, then he put his lantern on the ground and rushed at me with both hands free. He was surprisingly strong for a thin man and almost knocked me over as he lunged for the package, but I kicked backward while covering the bundle with both arms, my foot landing hard in his stomach. Winded, he doubled over, and before he could gather himself for his next assault, I threw a punch with my bandaged right hand, catching him on the chin and sending a bolt of pain up my arm. He stumbled back, then unexpectedly rallied and threw himself forward at my legs, knocking me to the ground. I heard my back crunch as I hit the flagstones and I tried to wrestle the package beneath me but he had the advantage of weight and quickly straddled me, pinning me to the ground. His face was almost in mine as he grasped the papers; I feared he would tear them as he tried to prise them from my grip and a sudden surge of anger redoubled my efforts to protect them.

"Hand those to me, Bruno-you are meddling in matters you do not understand," he hissed through his teeth; I could smell his sour breath in my nostrils.

"You do not even know what I have here," I spat back, clutching the papers to my chest.

"Whatever you have removed from a student's room is the property of the college in that student's absence," he whispered, still pompous even as he scrabbled at my hands.

"Why do you want it so urgently?" I hissed back. "Because you didn't manage to find it when you turned the room upside down yourself? Do you always help yourself to keys while Cobbett is sleeping?"

"The question, Bruno," he said, his nostrils flaring, "is how you knew what to look for and where to find it? It can only be that you are part of the papist conspiracy. But who would expect otherwise of an Italian? The rector is a gullible fool but I always saw through you."

"It is you who is out of your depth," I grunted back, bucking my back to try and throw him off balance, "but I am no papist and those who matter know that."

"You will give me those papers, Bruno," he panted, shifting his weight so that he was bending right over me, his nose almost touching mine, "or I will rouse the whole college. With three of our number newly dead, you will be locked up in the Castle prison before you have a chance to fashion your latest implausible tale."

So Slythurst was against the papists, I thought, as his knee dug into my chest. Then why was he so keen to cover up evidence of the murders? What did he want with the papers I was now fighting to keep out of his grasp, that he had ransacked first Mercer's and now Norris's room in search of them? Whatever his purpose, I knew no one must have those papers but Walsingham, and that I must deliver them to Sidney by my own hand. As I felt the package begin to slide from my damaged hand, I mustered all the reserves of strength I had left. Clenching my jaw, I sat up as far as I could, my face so near to Slythurst's that it might have seemed I was about to kiss him, then drew my head back slightly and jerked it sharply up, so that my forehead hit him squarely in the nose with a smart crack. He let out a howl, clutching both hands to his nose, and I took the opportunity to throw him off balance and roll away. A dull pain swam across my head and my vision blurred, but it seemed he had come off the worse; when he took his hand away I saw his nose was bleeding copiously. Above my head another light approached, swaying, accompanied by a slow shuffle of footsteps.

"What in God's name-?" Cobbett began, lifting his lantern and stopping with a frown of amazement to see me and Slythurst brawling like drunkards in the middle of the quadrangle. I noticed that in his other hand he carried a sturdy stick. "Doctor Bruno? Lord, you look a right state. How did you get in?"

"Long story, Cobbett," I said, hobbling to my feet. "I need your help."

"Seize him, Cobbett!" Slythurst cried, the words muffled by the hand still clamped to his broken nose. "He has stolen property-as a Fellow of this college, I order you to apprehend him!"

Cobbett looked from Slythurst to me with some concern. I grabbed his sleeve and wheeled him away, out of Slythurst's earshot.

"You must believe me, Cobbett-this is a matter of utmost urgency. I think I know where to find the killer, and others may die tonight if I don't act." Seeing that he still looked uncertain, I added, in a whisper, "Sophia is in danger. I have to go this moment-tell me, where will I find my horse? He is in the rector's stable, I understand."

"Cobbett, do not open the gate! This man must not leave the college buildings with that package, do you understand?" Slythurst sounded desperate now; lurching to his feet, he lunged unsteadily again at me, and though I was still dizzy from the impact of the last blow, I hurled myself at him, my teeth bared.

"Ne vuoi di piu? Fatti sotto," I snarled, pulling out the kitchen knife I had removed from Humphrey Pritchard and thrusting it before me. "Come on then, if you want some more."

Slythurst may not have understood my words but he could not mistake the meaning of the knife; he took a step back, stared at me defiantly for the briefest moment, then raised his head and screamed out "Murder!" with all the force of his lungs. On two sides of the quadrangle a number of windows creaked open and shadowy figures leaned out, alarmed by the disturbance.

"I must go this instant," I whispered to Cobbett, still holding the knife out toward Slythurst, who had clearly decided his best hope was to wake the whole college and set them to apprehend me.

"He will have the watch on you," Cobbett muttered, as Slythurst raised his cry of "Murder!" again. "You will need to ride fast if you hope to leave the city. The rector's stable is almost directly opposite, on Cheney Lane. Come." And the old porter ushered me toward the main gate, moving at a pace I had never seen from him before.

"I must get these papers to Christ Church," I hissed, as he unlocked the gate. Slythurst watched us but made no move toward us this time; he seemed to have decided to wait for reinforcements. "Which is the best way?"

Cobbett shook his head. "If you ride to Christ Church now, they will apprehend you before you can leave the city," he whispered, barely audible. "Give the papers to me-I will send a messenger I trust."
