"Murder was rarely a tidy business. Whether it was craftily calculated or wildly impulsive, it tended to leave a mess for others to clean up". Eve's job is to do exactly that. As a Lieutenant of the NYPD, she stands for the dead, and seeks justice for them.
In "Judgment in death", the 12th book in J. D. Robb's futuristic "In Death" series, the victim is another cop, Taj Kohli. He was killed while working undercover in an exclusive nightclub, that casually belongs to no other than Eve's husband, Roarke. Matters complicate further when it appears than a shady and powerful character, Max Ricker, is somehow involved in detective Kohli's death. Ricker is a former associate of Roarke that nurses a grudge against him, and wants to make Roarke pay for deciding to go solo a long time ago. As if that weren't enough, Eve's investigation uncovers police corruption, and she has to decide who is to be trusted.
I think you are likely to appreciate the fact that recurring characters of the series appear in "Judgment in death" too. I strongly advise you read these books in order, so that you will have the opportunity of getting to know the characters slowly, and of watching them grow. Of course, my favourite interactions are those between Eve and Roarke, but there are plenty of other interesting characters, like Peabody, McNab, Captain Feeney and Doctor Mira. We even have a cop from Internal Affairs with a very big crush on Eve, something that Roarke will not take well :)
All in all, I really liked this book. The reasons for that are many: it has lots of action, a good plot and plenty of interesting characters. Due to all that, I recommend "Judgment in death" to you. Beware, though: the "In death" series is addictive!!
