When BBC dvd started releasing Silent Witness on dvd we had to wait along time after series 2 before the 3rd series was released with series 4. Now thankfully they seem to be releasing them at a quicker rate. As the other reviewer pointed out this dvd which contains series 9 and 10 does not feature Sam Ryan. I fact Sam Ryan left at the end of the 1st story A Time To Heal in series 8 when Amanda Burton decided to leave to move on. Now we have Nikki Alexander who joined the series in the series 8 story Nowhere Fast. Nikki is superbly played by Emilia Fox and joins regulars Loe Dalton (played by William Gaminara) and Harry Cunningham (played by Tom Ward) - the 3 have an excellent on screen chemistry.
The picture and sound quality are excellent and the dvds are nicely pacaged in a sturdy plastic amary style case. Series 9 concists of the following episodes Ghosts, Choices, The Meaning Of Death and Mind And Body. While series 10 has the following stories Cargo, Terminus, Body Of Work, Supernova and Schism. Silent Witness is one of the best tv programmes the BBC make and I hope the nest series is released on dvd soon.
