Sandra assigns UCOS to reinvestigate the murder of Dr. Simon Lockhart 30 years ago. The victim was found dead in a stall at Smithfield meat market, but the stall holder, Harry Eldridge, disappeared before he could be questioned, and later turned up dead with his body cut up neatly. Questions are raised over the way Lockhart interacted with Eldridge, and the fact the dead butcher was not as good a man as people make him out to be. But for Sandra, a personal matter soon leads her to making a shocking personal connection with the case.
