Kudos to director Toby Frow who managed to take the same cast that had been flailing around in the other episodes and stitch together a convincing and well-acted story. True, the plot was full of the typical credulity stretching twists and turns, but it held together and this pattern is nothing new for "Silent Witness". What was different is that the ingredients came together in a way that had been absent before and made for a very effective drama. You could see all the actors raise their game, even the romance between Jack and Nikki was presented with a veracity that you just did not see in prior episodes. It made me wonder what on earth was going on during the rest of the season but at least provided strong reassurance that the show was not dead on its feet.
