Back then, Rina was a 20-something widow with two small boys; Peter was a police detective in his late 30s, divorced with a teenage daughter. We've seen them age in approximately real time, marry, and have a daughter who's now sixteen. Rina's sons are nearly grown, one in college and the other engaged to a fellow med student, and Peter's daughter is married and after nearly a decade as a police officer has been promoted to detective. Peter's colleagues are aging too, and the book has a bit of a 'changing of the guard' feel. I suspect that Peter will retire around book 20, and Detective Cindy Decker Kutiel will follow her father's footsteps into homicide.
That's in the future - in the present, we have the particularly brutal murders of a real estate developer, his wife, and a member of their household staff and the serious wounding of one of their sons. While Peter deals with department brass and press attention, Rina is serving on a criminal jury. During a break, one of the court translators (the blind man of the title) asks her to describe two men he's eavesdropping on. It's a bit too coincidental that they're discussing Peter's case, but Kellerman manages to prevent this from sinking the plot. She does this by both traditional methods (multiple suspects with multiple motives) and by making the translator seem a little creepy, and maybe a little too interested in Rina.
Blindman's Bluff is an average entry in the Decker/Lazarus series. That's actually a complement, because I've enjoyed every one I've read to date. Peter (with the help of his former partner Marge Dunn and her partner Scott Oliver) solves the case through a combination of plodding and luck, and using only clues which the reader sees. Maybe Kellerman could have mentioned age a bit less, and I would have liked a phone call from one or both of Rina's sons during the family scenes. Still, it's an enjoyable, well-paced novel which left me ready for book #19.
