At the worktable in his private study during the dinner hour, Snape set aside the empty vial that had contained a half ounce of Hermione's blood, and, lifting the small glass cauldron, he held it up to the light of a torch burning in a bracket on the wall.
His right arm ached at the effort of pouring the contents of the cauldron into a beaker.
He must drink it down in one draft. It tasted vaugely like dill and pepper. When he had finished drinking it he stood a moment registering in his mind its effects. Then he said, "Dictation."
A quill rose from an ink bottle. It tapped its point on the bottle rim to expell the excess ink, then poised itself above the open journal on the worktable.
"Entry for Saturday of the third week in September, Nineteen Ninety-four."
The quill got busy writing in a fluid cursive.
"The anti-vampiric potion type B has instantly relieved the pain of the wound," Snape dictated impassively. "There is a dryness of the mouth and a slight thirst for mother's milk. This is a positive sign, suggesting that--"
A knock on his study door. He turned from the table and said, "Yes?" in a tone of annoyance.
It was Trelawney. "May I come in?"
"Seeing as how you are already in, it would be redundant of me to extend an invitation to come in. Who is that with you?"
"Come, dear," said Trelawney, urging Mrs Dursley into the room.
Petunia glanced around with a renewed sense of curiosity and revulsion. She could hardly bare to look at the specimens in jars on the black-lacquered shelves.
"May I?" Trelawney took the long curling leaf from Petunia and walked up to Snape with the leaf held in front of her thick glasses. She was acting out her usual trance state.
"Albus asked me to describe to you what I experienced when I first touched this leaf," she was saying in an otherworldly voice. "Mrs Dursley found it in her hair, after sixth period Muggle Studies on Friday. Charity brought it to my attention, and... Oooh.. the vibrations! The visions!"
Snape glared down at her with stoic impatience. "Proceed."
Trelawney was in full divination mode. "A stupendous revelation is coming! A bird in the hand is worth two in... in the cave. And what is found must be lost! Oh it must be lost, or terrible things will manifest in the life of she who... who clings to what must not be kept!"
Trelawney lowered the Bloodwort leaf and shook her head as though to disconnect with the Other Side.
Snape noticed the pallid face of Mrs Dursley. She had evidently heard this gibberish before, doubtless in Dumbledore's office. Now she received back the leaf with a look of incomprehension.
"Thank you, dear," said Trelawney to her, smiling sweetly.
Charlie appeared in the doorway and pretended to knock. "All here and accounted for, Professor," he said, and stepped back to let Trelawney and Petunia exit into the long torchlit corridor.
Giselle, Hermione, and Harry stood near the bottom of the Dungeon entrance stairway. They leaned back against the wall as Trelawney and Mrs Dursley came up the corridor.
Petunia stopped in front of Harry, eyeing him a little reproachfully, Giselle thought.
"I am leaving Monday morning," said Petunia to her nephew.
Harry nodded slowly. "It's been nice having you visit the school," he said.
"I don't see how any sane person can tolerate this 'school' for very long."
Harry swallowed painfully. "It's like a home to me, the only real home I've had," he said, and just then saw Ginny Weasley walk by the top of the stairs, with Ron and Dean Thomas. "And the Burrows," he added, "that's like a home to me also."
Mrs Dursley smiled tautly, her eyes narrowing. "You've another home, you know, where I'll be seeing you in June," she said, "if you survive this place."
With that she went on up the stairs, Professor Trelawney following. There came a sudden breeze through the Hall. Giselle saw the Bloodwort leaf swirling up over Mrs Dursley's head, to settle in her hair.
That should have amused Giselle, but it didn't. There was something about it that disturbed her.
'Well,' she thought, 'it was good of Mrs Dursley not to mention to Harry that she knows about his mother haunting the castle, haunting it in some troublesome way. Maybe Dumbledore told her to keep quiet about it.'
"Let's go!" Charlie called to them.
When they were all in the study, Snape said, "Come with me," and went to the round-topped wooden door that led to his office.
Here he went to the bare wall across from his desk where a large rectangle had been drawn on the wall with chalk.
"A full-size portrait of Titus the Terrible hung at this spot," he said. "It has been stored away for safe keeping. Miss McGonagall, come here if you please."
Giselle, surprised, walked over to him with a hand on her chest. She could feel her heart thumping.
"I am going to put you into an hypnotic sleep," Snape said to her. "You will do as directed. It will require only a minute. Relax and breathe normally."
Easier said than done, she thought. She tried to relax, but her body seemed made out of vibrating wood.
Then suddenly she felt comfortably dreamy and carefree. She thought it was quite the thing to do for her to hold hands with Snape. She knew that they were all holding hands: Charlie, Harry, Hermione, Snape, and herself; a sort of game, like getting ready to play Ring Around The Rosie.
"Go into the passage," Snape said to her.
Of course, the passage! It was right there in front of her. She stepped into the passage and went on for a few more steps until they were all there with her.
"Release hands," she heard Snape say, and with a strange reluctance she let go of his hand.
He snapped his fingers in her face.
"Oh!"
She saw now that she had somehow walked through the wall of Snape's office, leading the others along. It was a narrow passage, full of blue shadows, like a dry fog that smelled of old shoes. The walls, low ceiling, and uneven floor were studded with what looked like sapphires. It was drafty and cold, going straight ahead and then curving to the left. When anyone spoke, there were soft echoes of the speech, like a ghostly chorus following them.
"Pay strict attention," Snape was saying. "I will lead, and Mr Weasley will bring up the rear. McGonagall will come behind me, then Granger and Potter. Mr Weasley has cast upon us a Spell Delay shield. He is expert at it, having performed it many times to help protect himself from dragons and other adversaries. It will give you a few precious seconds to respond to any spells cast at you."
Giselle, Hermione, and Harry exchanged looks. This was not supposed to be risky. Perhaps it was just a precaution...?
"Keep this in mind," Snape continued. "High level spells may be either real or an illusion. The rule of thumb is this: if you find yourself in an utterly different environment, an obviously threatening one, it is probably an illusion meant to unnerve you, to distract you. A simple disillusion counter spell will get rid of it. But if an effect is something occuring in your true environment, it is probably an actual thing. Deflect it or reinforce your shield before countering with a hex of your own."
Giselle turned nervously to Harry and Hermione. She was sure that they were all remembering Moody's dictum: 'Constant vigilance!'
"Sir," said Harry. "What are we supposed to be looking for? And what IS this place anyway?"
Snape had turned to go down the passage. He looked back at Harry and said, "Our expedition is to discover where this complex of passages leads to. And in particular to find the living portrait responsible for it, a rogue portrait who can move about like a ghost. Any such person we encounter is to be stunned immobile. Now, follow me, and no talking."
Giselle sensed that there was more to the expedition than just the apprehension of Sanguino. As she followed close behind Snape she wondered if they would come across Harry's mother, and how Harry would react if they did. Poor Harry! He might be in for a really awful surprise.
Or maybe it wouldn't be awful, she thought as they turned the corner into a wider, higher passage. Maybe he would be glad, maybe overjoyed, to see the ghost of his mother. It would all depend, Giselle thought, on the circumstances.
In the dimly lit Infirmary of the hospital wing, Leon Vlaud struggled out of bed. Every joint of his body was aching.
But it wasn't that which got him on his feet.
"Thirsty?"
Leon stared at the opposite wall, where, between two beds, stood a familiar figure in a dark brown robe and red turban.
"Sanguino!"
The semi-transparent wizard chuckled. "I have something for your thirst," he said, motioning for Leon to come to him. "I can not stray far from the walls. Come, if blood thirst assails you. Your deliverance awaits."
"Where is my son?" growled Leon, his hands massaging his burning throat.
"Did I not promise him a cure? He is at St Mungo's."
"That was not your idea," Leon said, walking painfully across the aisle. "It was Dumbledore. He has eyes and ears everywhere. Lucius is a damn fool, I see that now. And your selfish agenda will just as certainly fail. God, I am burning up for blood! Help me!"
"Help you?" said Sanguino. "Why not? You have helped ME, yes, by being the guinea pig for my experiments with the fledgling Roc. Of course it was the draconic bird that bit you. Septima Vector told me so earlier this evening. She was the one who suggested I try quenching your thirst with... Well, come! Don't take all night! Follow me through the wall, where the portrait of Augusta of Salem so proudly hung. Come, take my hand!"
Leon lunged for the proferred hand, his breath wheezing from his parched mouth. He was pulled forward into a bluish darkness.
"There," said Sanguino, pointing to a elderly wizard in chains who stared back at Leon with hollow eyes. Beside the figure was Minx, stooped and shivering. Sanguino pushed the elf aside.
"Quench your thirst, Vlaud! The blood is pumping through the jugular vein of Titus the Terrible! I have built him up for you, yes, on the instructions of Vector. He is weakening as you stand there. Do not delay."
Leon cried out, his hands gripping the shoulders of the hapless Titus as the portrait dropped to its knees under the onslaught of Leon's gouging teeth.
Sanguino watched for a few moments, his tongue wetting his lips. Then he turned his back on the brutal feast and said to Minx,
"Tell Hexaba to meet me in the Chamber of the Pigments."
The elf bowed. "Be warned that Severus Snape and his cohorts have entered the domain," he announced in a shaky voice.
"All the more reason to prepare in the Chamber where my powers are greatest. Tell Hexaba that Lily Potter is to be sacrificed. She will understand what you mean."
"What you say, I do."
"And one more thing," Sanguino said, wiping saliva from his beard, "tell her that she will have her chance to kill Charles Weasley. Vector has assured me that he will accompany Snape."
Minx went scurrying off down the sloping passage until he vanished in the dense blue fog.
