“My uncle,” she replied absently.

It was a relief to see the gates of the Red Keep looming large before her. She gave Tommen over to the charge of his squires and retired gratefully to her own chambers to rest.

No sooner had she eased off her shoes than Jocelyn entered timidly to say that Qyburn was without and craved audience. “Send him in,” the queen commanded. A ruler gets no rest.

Qyburn was old, but his hair still had more ash than snow in it, and the laugh lines around his mouth made him look like some little girl’s favorite grandfather. A rather shabby grandfather, though. The collar of his robe was frayed, and one sleeve had been torn and badly sewn. “I must beg Your Grace’s pardon for my appearance,” he said. “I have been down in the dungeons making inquiries into the Imp’s escape, as you commanded.”

“And what have you discovered?”

“The night that Lord Varys and your brother disappeared, a third man also vanished.”

“Yes, the gaoler. What of him?”

“Rugen was the man’s name. An undergaoler who had charge of the black cells. The chief undergaoler describes him as portly, unshaven, gruff of speech. He held his appointment of the old king, Aerys, and came and went as he pleased. The black cells have not oft been occupied in recent years. The other turnkeys were afraid of him, it seems, but none knew much about him. He had no friends, no kin. Nor did he drink or frequent brothels. His sleeping cell was damp and dreary, and the straw he slept upon was mildewed. His chamber pot was overflowing.”

“I know all this.” Jaime had examined Rugen’s cell, and Ser Addam’s gold cloaks had examined it again.

“Aye, Your Grace,” said Qyburn, “but did you know that under that stinking chamber pot was a loose stone, which opened on a small hollow? The sort of place where a man might hide valuables that he did not wish to be discovered?”

“Valuables?” This was new. “Coin, you mean?” She had suspected all along that Tyrion had somehow bought this gaoler.

“Beyond a doubt. To be sure, the hole was empty when I found it. No doubt Rugen took his ill-gotten treasure with him when he fled. But as I crouched over the hole with my torch, I saw something glitter, so I scratched in the dirt until I dug it out.” Qyburn opened his palm. “A gold coin.”

Gold, yes, but the moment Cersei took it she could tell that it was wrong. Too small, she thought, too thin. The coin was old and worn. On one side was a king’s face in profile, on the other side the imprint of a hand. “This is no dragon,” she said.

“No,” Qyburn agreed. “It dates from before the Conquest, Your Grace. The king is Garth the Twelfth, and the hand is the sigil of House Gardener.”

Of Highgarden. Cersei closed her hand around the coin. What treachery is this? Mace Tyrell had been one of Tyrion’s judges, and had called loudly for his death. Was that some ploy? Could he have been plotting with the Imp all the while, conspiring at Father’s death? With Tywin Lannister in his grave, Lord Tyrell was an obvious choice to be King’s Hand, but even so. “You will not speak of this with anyone,” she commanded.

“Your Grace may trust in my discretion. Any man who rides with a sellsword company learns to hold his tongue, else he does not keep it long.”

“In my company as well.” The queen put the coin away. She would think about it later. “What of the other matter?”

“Ser Gregor.” Qyburn shrugged. “I have examined him, as you commanded. The poison on the Viper’s spear was manticore venom from the east, I would stake my life on that.”

“Pycelle says no. He told my lord father that manticore venom kills the instant it reaches the heart.”

“And so it does. But this venom has been thickened somehow, so as to draw out the Mountain’s dying.”

“Thickened? Thickened how? With some other substance?”

“It may be as Your Grace suggests, though in most cases adulterating a poison only lessens its potency. It may be that the cause is. less natural, let us say. A spell, I think.”

Is this one as big a fool as Pycelle? “So are you telling me that the Mountain is dying of some black sorcery? ”

Qyburn ignored the mockery in her voice. “He is dying of the venom, but slowly, and in exquisite agony. My efforts to ease his pain have proved as fruitless as Pycelle’s. Ser Gregor is overly accustomed to the poppy, I fear. His squire tells me that he is plagued by blinding headaches and oft quaffs the milk of the poppy as lesser men quaff ale. Be that as it may, his veins have turned black from head to heel, his water is clouded with pus, and the venom has eaten a hole in his side as large as my fist. It is a wonder that the man is still alive, if truth be told.”

“His size,” the queen suggested, frowning. “Gregor is a very large man. Also a very stupid one. Too stupid to know when he should die, it seems.” She held out her cup, and Senelle filled it once again. “His screaming frightens Tommen. It has even been known to wake me of a night. I would say it is past time we summoned Ilyn Payne.”

“Your Grace,” said Qyburn, “mayhaps I might move Ser Gregor to the dungeons? His screams will not disturb you there, and I will be able to tend to him more freely.”

“Tend to him?” She laughed. “Let Ser Ilyn tend to him.”

“If that is Your Grace’s wish,” Qyburn said, “but this poison. it would be useful to know more about it, would it not? Send a knight to slay a knight and an archer to kill an archer, the smallfolk often say. To combat the black arts. ” He did not finish the thought, but only smiled at her.

He is not Pycelle, that much is plain. The queen weighed him, wondering. “Why did the Citadel take your chain?”

“The archmaesters are all craven at heart. The grey sheep, Marwyn calls them. I was as skilled a healer as Ebrose, but aspired to surpass him. For hundreds of years the men of the Citadel have opened the bodies of the dead, to study the nature of life. I wished to understand the nature of death, so I opened the bodies of the living. For that crime the grey sheep shamed me and forced me into exile. but I understand the nature of life and death better than any man in Oldtown.”

“Do you?” That intrigued her. “Very well. The Mountain is yours. Do what you will with him, but confine your studies to the black cells. When he dies, bring me his head. My father promised it to Dorne. Prince Doran would no doubt prefer to kill Gregor himself, but we all must suffer disappointments in this life.”

“Very good, Your Grace.” Qyburn cleared his throat. “I am not so well provided as Pycelle, however. I must needs equip myself with certain. ”

“I shall instruct Lord Gyles to provide you with gold sufficient for your needs. Buy yourself some new robes as well. You look as though you’ve wandered up from Flea Bottom.” She studied his eyes, wondering how far she dared trust this one. “Need I say that it will go ill for you if any word of your. labors. should pass beyond these walls?”

“No, Your Grace.” Qyburn gave her a reassuring smile. “Your secrets are safe with me.”

When he was gone, Cersei poured herself a cup of strongwine and drank it by the window, watching the shadows lengthen across the yard and thinking about the coin. Gold from the Reach. Why would an undergaoler in King’s Landing have gold from the Reach, unless he were paid to help bring about Father’s death?

Try as she might, she could not seem to bring Lord Tywin’s face to mind without seeing that silly little half smile and remembering the foul smell coming off his corpse. She wondered whether Tyrion was somehow behind that as well. It is small and cruel, like him. Could Tyrion have made Pycelle his catspaw? He sent the old man to the black cells, and this Rugen had charge of those cells, she remembered. All the strings were tangled up together in ways she did not like. This High Septon is Tyrion’s creature too, Cersei recalled suddenly, and Father’s poor body was in his care from dark till dawn.
