Book Review: Cross and Burn

Format: Kindle

From Goodreads: Cross and Burn, picks up where The Retribution left off: following the best crime-fighting team in the UK-clinical psychologist Tony Hill and police detective Carol Jordan-who when we last saw them were barely speaking, and whose relationship will now be challenged even further.
Guilt and grief have driven a wedge between long time crime-fighting partners psychologist Tony Hill and ex-DCI Carol Jordan. But just because they're not talking doesn't mean the killing stops.
Someone is killing women. Women who bear an unsettling resemblance to Carol Jordan. And when the evidence begins to point in a disturbing direction, thinking the unthinkable seems the only possible answer. Cornered by events, Tony and Carol are forced to fight for themselves and each other as never before.

Thoughts: You know when a new book in the series you love comes out and you read it and it goes way too quickly and then you're all in a funk because it's over and the author has not yet written the next book? Yeah, that's me as I write this review.
Cross and Burn is the latest installment in Val McDermid's Tony Hill and Carol Jordan series. The BBC made a fabulous TV series based on the series called Wire in The Blood. Robson Green was a perfect Tony Hill.

Hmmm, Robson Green....

Anyway, the previous book in the series left Tony and Carol in a not good place. A major rift formed in their friendship, MIT was disbanded and it's members scattered, Tony was cut loose due to budget cuts and Carol had quit the force.
But yet another serial killer is on the loose and it could have dire consequences for both Tony and Carol.
McDermid keeps her plots moving at a rollicking pace. Discoveries are constant and help push the storyline along. Unlike many reoccurring characters in books of this genre, McDermid's characters have not become annoying one dimensional people whose constant issues are whined about incessantly and never resolved in any way. McDermid's characters have issues, but they learn and grow from them or at least accept them as personality traits they aren't willing to change and therefore don't moan about! 
My dilemma now is what next? Something from a different genre? A different book by McDermid? (she has other series' and stand alones, but I have never been able to get into them) or go back and re-read Tony and Carol from the beginning? What would you do?
