"Wait...." Marlene was processing what Tess was telling her. There was something off. "No, hold on.<a class="link link--external" data-proxy-href="/proxy.php?link=https%3A%2F%2Fwww.ncbi.nlm.nih.gov%2Fpubmed%2F1585880&amp;hash=01c25c12bc75c370b62f069dd6c32ff9" href="https://www.ncbi.nlm.nih.gov/pubmed/1585880" rel="nofollow ugc noopener" target="_blank">Frostbite can only occur ante-mortem</a>. Tissue frozen post-mortem simply freezes, like the pork chops in your freezer. Tissue frozen Ante-mortem exhibits burst blood vessels and a deep purple colouration. Tissue that is frozen peri-mortem would exhibit mild signs of frostbite, like the early stages, as the blood ceased to circulate anyway. So the victim was killed somewhere cold, but not kept there for any length of time. You say on the leg? Specifically what part of the leg? And more specifically,<i>not</i>on the toes? Those are the usual places for frostbite, the extremities: toes, fingers, ears and nose. For there to be frostbite in one location on one leg only, my theory is that the killer cut the leg off and laid it against something that was extremely cold for a few minutes."<br/><br/>She paused. "What sorts of places have pipes or divices that would be capable of producing frostbite in just a few moments of contact? Sybil, process previous enquiry."<br/><br/>"So... What now? This is my first case. We have a number of lines of enquiry, should we try following some of them up?"<br/><br/>Thunder rolled again and as the rain hammered down now, Marlene started the car and instructed it to head back to the Bureau HQ. They were about halfway there, and just about to pull away at a green light when a bright red sports car shot through the junction doing at least a hundred KPH. Marlene yelped in fright, then hissed, "Manual Control, Pursuit Mode!" And stamped on the accelerator as the lights and siren started up. This she was good at. She had excelled in pursuit driving. As the car hit one twenty, the control surfaces snapped out and the anti-gravity boots kicked in, slewing the car up into the air as she crossed an intersection. "Call it in. Bright red Ferrari. Registration one one two M O zero five. Fuck, the thing's brand new! Heading South on Princess Road doing over a ton in a fifty limit, am in pursuit, requesting back-up."<br/><br/>Her blood was flowing and her adrenalin was pumping as she tooled the hovercar along over the roofs of the other vehicles that the target vehicle was weaving in and out of. Soon enough they were right behind the target. The driver was now making random turns in a vane effort to loose his pursuers. The police vehicle was registering a crime coefficient of almost a thousand from within. Marlene waited until they were on a clear stretch of road and then ordered the car, "Deploy the buffers." Huge soft pads of tangled polymers suddenly erupted from the front of the police car. Buffers, or to give them their official name, Rapid Expansion Vehicle Emergency Restraint System (REVERS - but no-one ever called them that), were made from memory-polymer. Compressed into cubes the size of a coconut, when released they expanded almost instantly, the polymer strands tangling and twisting as they did, into a cube 2m on a side. The speeding car stood no chance as it ploughed into the soft but unbreakable strands which instantly wrapped around every moving part, bringing the vehicle to a rapid but safe stand-still.<br/><br/>Marlene was grinning as she landed her car behind the Ferrari, which had been reported as stolen from a dealership just ten minutes earlier. Weapon drawn, wary of the coefficient still in the high nine-hundreds, she moved quickly towards the car, then glanced back, hoping that Tess was following procedure and covering her.
