'Take us to her.' Anastacia ordered. Herself, Beth and Brad were led down a few corridors, until they found themselves in the same corridor that Anastacia had met up with Ginny in earlier. Ginny was lying on the ground, a pool of blood around her head and her skin ghostly white. Professor Snape was standing by her.

'I thought you'd gone back to your class.' Beth said suspiciously.

'I was going back to my class – but I have to go this way. I found her, and called Minerva.'

'I just happened to be walking back to my office, and found Severus taking Minerva from her lesson.' Dumbledore added.

'Wasn't Ginny meant to be in your class?' Anastacia asked McGonagall.

'She was. She seemed very absent-minded and panicky, though, and then she suddenly had a kind of "panic attack". She just burst into tears and kept on saying, "I need to tell them, I need to tell them!" So I took her to hospital wing – Madame Pomfrey wasn't there, so I told her to wait. I went back up to the classroom, and then a few minutes later Severus runs into the room, saying that Miss Weasley was lying outside the classroom, dead.'

'All right.' Anastacia said. 'Do what you will with her parents and the school, but the show's over now. Leave the body to us.' 

Dumbledore was the first to leave the corridor, muttering something about, 'bad impressions on the school' and 'how am I going to tell Molly and Arthur?' Snape went back down to his dungeon classroom, looking even paler than usual, and McGonagall eventually returned into her classroom. Anastacia, Beth and Brad heard her telling her class that 'all will be explained later.'

Anastacia pulled her wand from the pocket of her robes, and levitated Ginny's body a few feet off the ground. They then took her to the hospital wing, where Dumbledore had told Madame Pomfrey to prepare a bed for Ginny's body.

When the three detectives reached the hospital wing, Madame Pomfrey was waiting for them. She looked like she'd been crying. Dumbledore had warned her before he had gone back to his office.

'Please may we use one of your beds?' Anastacia asked. Poppy Pomfrey nodded, and ushered the three detectives into a curtained-off cubicle. Anastacia moved Ginny's body onto the bed, and Poppy left them to do what they needed to do.

Anastacia inspected Ginny's body closely, before turning to her colleagues. 'She was killed by a blow to the head. Her skull is completely shattered at the back of her head. Her murdered obviously came up behind her and hit her with something, hard.'

'What do we do now?' Brad asked.

'We talk to Madame Pomfrey.' Anastacia replied, leading Brad and Beth from the cubicle. Poppy Pomfrey was sitting at her small desk at the far end of the hospital wing. When she saw the three people coming towards her, she hurriedly stood up.

'May we ask you some questions?' Anastacia asked.

Poppy nodded, and with a wave of her wand pulled three extra seats up to her desk. They all sat down, and then Anastacia said, 'We were told that when Ginny was brought here, you weren't there. Is that true?'

'I just popped out to get a glass of water.' Poppy replied defensively.

'We are not blaming you, all we need to know is whether the facts we have are correct.' Beth said.

'Miss Weasley was not here when I left the hospital wing, and she was not here when I returned. This is the first time I have seen her today.'

'Thank you, that is all we need to know for now. One last thing – Miss Weasley was killed by a blow to the head. If she was killed here, the murder weapon could have quite possibly have been taken. Can you look out for anything that seems to have gone missing.' Anastacia said. Poppy nodded, and Anastacia, Beth and Brad left the hospital wing.

'So, either McGonagall is lying and she never took Ginny to the hospital wing, or she had left it again by the time Madame Pomfrey returned.' Anastacia summed up the facts they knew.

'Ginny could have left of her own will.' Beth added.

'So she could have been murdered anywhere in the school. I think she was actually killed in the hospital wing – if she had been killed in a corridor, the nearest classes would probably have heard something. If she was murdered and then taken to where she was found, the murderer would confuse things for us, but it would also make everything make sense. So now we need to work out who could have possibly done this.'

'Most students would have been in classes, and no one can apparate inside Hogwarts. That makes it most likely to be a teacher… or a rogue student.'

'Also, if we go back to the case of Miss Granger, only Hogwarts teachers can apparate onto the Hogwarts Express. So, unless we have some stowaway hiding somewhere in this castle, who came on the Hogwarts Express, it can only be a student or teacher.'

'You think it's the same murderer for both girls?' Brad asked.

'Most likely. Right, we still need to talk to the Death Eaters present at that meeting – they might give some useful information about the teachers or students here, even if they are not suspects themselves. Also, I want a list of any students who were out of class at the time of Miss Granger's murder.' Anastacia ordered. 'Brad, you do that. Beth, I want you to talk to the teachers – see who can't come up with evidence of where they were at the time of both murders. I'll start on the Death Eaters.'

***

Anastacia was getting ready to go to the house of the first Death Eater on the list Severus Snape had given her – Ronan Halliwell, when Brad hurried up to her.

'I've spoken to every teacher who was teaching at the time of Miss Weasley's murder. No one had any absent pupils, apart from Ginny herself.'

'Good, that limits it even more. It must be one of the members of staff.' Brad then handed her a list.

'All the teachers who were teaching at the time of the murder.'

Anastacia looked down the list. Nearly all the members of staff were there, all apart from McGonagall and Snape. Snape had found the body, and McGonagall had been the last to see Ginny alive. She had been out of the lesson when the murder most likely took place.

'Professor Dumbledore doesn't teach.' Anastacia said, reaching the bottom of the list and seeing Dumbledore's name.

'He was in the grounds with Rubeus Hagrid, and as you saw he only appeared once Ginny was dead. He and Hagrid have exactly the same story.'

'Fine. You'll make Sergeant at this rate, Brad.' Anastacia said, smiling at her young friend before going on her way again.

***

Brad had shown Beth the list of teachers and what they were doing at the time of the second murder, but she still needed to find out who couldn't be accounted for at the time of the second murder.

Lessons had finished for the day, and all the teachers were congregated in the staff room after they had had dinner. They were all chatting about the day they had had, and especially Ginny's murder. A few days had now passed, but most of the school was still in shock. All the Weasley boys had been allowed home to be with their families, but Dumbledore was trying his best to keep the school running normally, without change.

When Beth entered the room, the whole atmosphere changed into one of secrecy and suspicion. Beth knew that not all the teachers were 100% happy with the investigation; in their opinion it just distressed and confused everyone. Some of the teachers, though, had no problem with Beth, Anastacia and Brad. Surprisingly, one of those teachers was Snape – he had been perfectly friendly to all three of them since they had arrived, and had never showed much hostility, apart from the time he got taken out of his lesson when Draco was first interviewed.

When the teachers had relaxed again after Beth's entrance, she began to flit among the groups, trying to establish where everyone was at the time of Hermione's murder. Eventually, she came to the conclusion that all the teachers had been waiting for the Hogwarts Express in the staff room, apart from Snape, McGonagall, Flitwick and Sprout, who had been making the finishing touches to their house common rooms and dormitories, and Hagrid, who had gone down to Hogsmeade to greet the new first years. Flitwick, Sprout and Hagrid, though, were accounted for at the time of Ginny's murder, so the suspects were still Snape and McGonagall.
