crossed the sternum, then a second incision from the xiphoid process down to the groin, cutting through muscle and yellow body fat. Blood welled thickly from the incisions. Using his hands, he pulled the incisions apart, revealing the internal organs. Normally he would cut through the ribs and cartilage next, exposing the heart, lungs and trachea, but he wasn’t conducting an autopsy – he was looking for one very particular thing.
Looking up at the gallery, where a grim-faced Toshiko and Ianto had now joined Jack and Gwen, he nodded at Toshiko. She pressed a button on a remote control she was holding, and the image of Marianne’s torso, taken by Toshiko’s ultrasound scanner, flashed up on the high-definition screen that hung above the table. The colour-coding showed where the creature was – or where it had been. Palpating Marianne’s duodenum, Owen quickly located the right stretch of intestine. He could feel something in there more solid than pre-digested food. It seemed to shift slightly under his questing fingers. Reaching out to the instrument tray, he retrieved a couple of clamps and used them to secure either end of the organ, above and below the creature. A few strokes with a scalpel and he had isolated that entire section – about a metre’s worth of wet, pink flesh. He lifted it clear and placed it in a metal bowl, then placed the bowl on the table beside Marianne’s abused body.
Ianto, unbidden, had retrieved a large glass jar from storage. It had a lid that could be fastened securely on top, and nozzles top and bottom so that liquid or gas could be introduced or extracted. It was about the size of Marianne’s head. Owen had sometimes used it for chemical experiments, but it suited his purpose now. From his chemical store, he obtained some hydrochloric acid and poured it into the jar, along with some distilled water and various other chemicals. By this time, guessing what he was doing, Gwen had scoured the Hub for whatever scraps of food she could find – old pizza crusts, sandwiches, bags of sweets, stuff from the refrigerator, anything that could be used to replicate the internal environment of a digestive system. Owen tipped them into the jar. Within moments the mixture had turned cloudy and curdled, and the sharp smell of the acid had been replaced by something nastier and more faecal.
Owen retrieved the section of Marianne’s intestine from the metal bowl and held it up above the jar. This was going to be the tricky bit. Somewhere in the background, he could sense Jack bringing his revolver out of his coat, holding it ready in case the creature tried to escape, as it had from the receptionist at the Scotus Clinic.
Owen held the scalpel in steady hands, preparing to make the final cut. He held the length of intestine by one end, just above the clamp, and sliced vertically downwards. The cut gaped open, pressed by something heavy within. For a moment, Owen was worried that the creature wouldn’t relinquish its grip, but it must have sensed a change in the health of its host. Whatever means it used to maintain hold on the inside of the gut, whatever hooks or suckers it was using, had been released. As Owen watched, a slimy black and blue mass slid out of Marianne’s intestine and fell into the jar, splashing the liquid up the sides where it stuck in globs, which then slid down again to rejoin the mass.
Ripples spread across the surface of the liquid, but Owen thought he could see the creature moving, digging itself deeper into the biological muck.
‘Ladies and Gentlemen, meet Paul,’ he said, the first words he had spoken since he had found Marianne’s body. ‘Paul is formerly the occupant of Miss Marianne Till. Paul will be staying with us for a while. Please make him feel welcome.’ He gazed up at Toshiko. ‘Tosh, you’re the most technical one here, so I’m going to tell you what to do next. The hydrochloric acid and the scraps of food will resemble the contents of a gut, which will make Paul here feel at home. I don’t fancy keeping it like this, however – too messy and it’s going to stink to high heaven. What I want you to do is drain the jar in about four hours, and while you’re draining it, flush it through with nutrient solution. You’ll find bags of it labelled up in the fridge. Set up a
