Melinda Clarke is strapping on the leather for a return to 'CSI.' Clarke's fan-favorite character, Lady Heather, will appear in an April episode, according to Entertainment Weekly.

In the episode, the 'CSI' team investigates human pets. Yep, human pets. There's a murder in that subset of the dominatrix world and Lady Heather is called to consult on the case.

'CSI' creator Anthony Zuiker co-wrote the episode.

Lady Heather was last seen in 2008. Clarke is now a regular on The CW's 'Nikita.'

(S01E17) Just under the wire, Shark sneaks a new episode into the vast desolation of repeats that is March. This time, the plot concerns the racially-charged shooting of a drug dealer and his honor-student cousin by two cops. As usual, the true culprit is not the person who Stark initially charges with a crime, but rather the person who years and years of TV-watching has told us to expect it will be: the allegedly least-likely (and therefore, most likely) candidate. The actual mystery here is why Isaac backed off his opportunity with Raina in San Diego some episodes ago. Isaac's ready to explain that now, but Raina's not in the mood, initially, to listen. She's reasonably suspicious that Isaac might just amount to a whole sack of drama and what does she need with that noise?

This is one of the better episodes. The plot-reversals, double-reversals, and triple-bogie re-re-re-reversals are not so outrageous as to sink the whole enterprise, and this allows some room for good character interaction.
