'Okay, a woman in her mid thirties, bruises behind her knees and then what looks like a severe blow to the head. Rough guess that she has been dead for 2 to 3 hours.' John said while examining the body.

'So that meant he went for the back of the legs to knock her down, so when struggling to get back up he hit across the head.'

'You know what? Every time you do that, it still amazes me!' John said rising from the body.

'Better than hearing "Piss off" all the time I suppose. So as I was saying, the criminal looks as if he may be good at finding out weaknesses. A woman in a dress and heels, of course, take her out from behind the legs!'

John looks at Sherlock trying to figure out what must be going through his mind for all this to come so naturally to him.

'Lestrade must be right, he sounds like he has done this more than once.' Sherlock continued.

'He sounds a bit like Moriarty.' John said. Sherlock just looked at him almost as if there was hurt or maybe anger in his eyes.

'Sorry Sherlock, I didn't mean...' John said quickly.

'It's quite all right. Simple mistake.' Sherlock said trying to smile to encourage John it was okay.

John nods at Sherlock and smiles back at him. Lestrade comes walking over with Sally.

'So, what has the Freak worked out?'

'Can't you think of a better name than that? It's getting a bit repetitive!' Sherlock shot a glance at Sally.

'I can think of much worse. Just being polite!'

'Right come off it you two! So Sherlock, any ideas?' Lestrade asks stopping the argument progressing.

'He took a swing to the back of the legs, then as she struggled to get back up hit her across the head.'

'Right, okay. Thanks for that. Very helpful. The girl who witnessed it couldn't quite remember what happened. She just turned the corner to see her mum on the floor and her step dad running.' Lestrade says.

'It was a girls mum? And her step dad?' John says looking shocked.

'Yeah, a girl of 14. She had just come back from a friends house to find them arguing. They stopped immediately and said they were just going out and would be back soon. The girl was obviously curious and followed only to find out her mum had been killed.' Lestrade explained.

'Is the girl okay?'

'Well, she is shock so I don't think she can really react to all this at the moment.'

'Silly thing to say, I mean I'm not surprised!' John said eyes widening.

'Are you done with looking at the body?' Sally asks after speaking to another officer.

Sherlock looks at John.

'Yeah, I think that's enough.' John says to Sally.

'Good, we're going to take her to the morgue now.' Sally walks off and joins Anderson.

'So, what now?' Lestrade asks looking at Sherlock.

'Find the criminal, what else?' Sherlock says intimidatingly.

'Yes, I know. But have you got all you need to go on?'

'Any chance of talking to this girl?' Lestrade sighed.

'I'll see what I can do.'

Lestrade walks off to ask permission.

'Why do you need to talk to the girl?' John queries.

'If this criminal is anything like I think he is, there is no way he has gone into hiding. He will be acting as normal. Also he will probably return to the flat to explain to the girl her mum has gone out for a bit, so if he goes back to find her missing he will start getting suspicious.'

John just laughs. 'Brilliant again, Sherlock!'

'Not really, just common sense.' Sherlock strides off to find out whether its okay to see the girl from Lestrade.

A/N – I think I may be able to try and get another chapter up this evening at I'm not to busy! Let me know what you think so far! :)
