A few minutes later, I'd been unplugged, completed a few forms, gotten changed and met back up with John and Lestrade, before heading down to the morgue.

The body is layed out on the table for us to look at.

"This is Julia Stoner, thirty two. Died yesterday," Lestrade tells us as we surround her and dad and I instantly whip out our magnifying glasses to look at her. Lestrade watches us as we move the glasses up and down her body.

"Do people actually read your blog?" dad asks as the mental note comes forward to break the uncomfortable silence.

"Where d'you think our clients come from?" John questions, looking her up and down without a magnifyer.

"We have a website."

"In which you enumerate two hundred and forty different types of tobacco ash," John says harshly. "Nobody's reading your website." I straighten up and glare at him.

"It's very useful information, actually," I tell him. "You can tell a lot from a man's smoking habits." Dad is paying no attention. He seems to have found what he was looking for, and now he's making his way towards the door, unnoticed by John.

"Right then: dyed blonde hair; no obvious cause of death except for these speckles, whatever they are." He points at the small red marks which are dotted all over her body before he realises dad has already left. "Sophie, got anything more?"

"There's an indent on her left hand which shows the marks of a ring - too thin to be a wedding ring, I'd say engagement is more likely, considering her age." John nods, following me so far. "I don't know if you saw it, but there are also two little puncture marks on her right ankle. I would say she was poisoned." I look up at Lestrade. "When will we get back the results from the autopsy?"

"Molly said they should be back by tomorrow, earliest," he tells me. I bite my lip in contemplation and stride towards the doors dad left by. "Sophie, don't go pressurising her," Lestrade warns.

"I'm not, I'm going to help," I tell him truthfully. I've never actually performed an autopsy, but I've seen Molly do it several times and I know how do it back to front in theory. It shouldn't be hard to do in practice.
