As soon as I read Sue Grafton's earlier Alphabet Series books, Grafton became one of my favorite writers of light chick-lit detective fiction. She can be a terrific storyteller. After being badly disappointed by the skimpy, disorganized "G" and "H" stories, and buoyed by the more substantial "I" and (to a lesser extent) "J" book, I was looking forward to "K." When picking up "K," you have to wonder where the story can go, as Millhone herself admits: how in the world after all of this time is she going to be able to get to the bottom of a 10-month-old death with no clues?
I found much of the book fast-paced and engaging, with diligent, believable legwork. Certain characters and descriptions were interesting. Grafton created two memorable and likable victims. She gives them characteristics and a lifestyle that make them intriguing and make the reader want to know more. The book avoids the pitfall of venturing into out-of-its-depth "social commentary"; aside from a few scattered acerbic or snide remarks about pornography, the book is remarkably matter-of-fact and clinical. There is thus a lot of interest in the interrogations of people who knew the victims. The interviews are matter-of-fact and believable, but they are not terribly informative, and show how much the suspense and interest of the book is driven by making the main victim a girl-next-door-high-class hooker and would-be porn queen.
The twists in the plot that Millhone's investigation brings to light are generally believable (for example, one character's tampering with a crime scene and a jealous wife planting an item in a home). The "new" evidence she turns up is generally well-finessed to avoid the obvious question why the detailed police investigation fell flat.
But the book grows increasingly frustrating when it becomes clear that the routine interviews are all the book had to offer and that they are not adding up to much. By contrast to the victims, the suspects are poorly explored characters with no motives. A land developer is not introduced until late in the book, as a result of a fortuitous tape recording. The "community meeting" about the development is one of the sketchiest, most exaggerated, least believable descriptions in the book (Millhone supposedly "falling asleep" is a lame excuse for skimping on details). The crucial link between suspects is an awful, improbable gift clue of a photo (why would a killer choose to attack a victim when it would be impossible to thoroughly search the apartment for such items, much less let it be shot in the first place? What good did it do to "kill all the witnesses," a throwaway line explanation, if possibly and glaringly incriminating evidence was left behind?).
The payoff is a superficially (if at all) described land development scam with a pool electrocution killing on the side. Because the crime lacks intricacy and cleverness, the detection merely had to be, and is, serviceable and routine, if diligent, to uncover it. And, of course, it is assisted by plot contrivances like a hidden tape recorder, Berlyn's intervention, the photo, and the killer's attempt on Millhone's life. The last two of these are the most disappointing, but the story has too little payoff to offset any of them. The story also includes a regrettable and pointless coincidence (a "kinky sex" relationship between two victims) and depends on unexplained, implausible behavior (the killer blabbing supposedly ingenious murder plans to one of the victims). The melodramatic end scene where Millhone confronts the killer and is blasted with a stun gun, before the intercession of a "man in an overcoat," undermines her professionalism and is an abrupt, anticlimactic conclusion. The last-minute theme-type allusion to "returning from the darkness" of vengeance, tied to the book's leitmotif of "living in the darkness, in the night," is mere atmospherics, not meaningful substance.
The bottom line is that the highly charged premise and interesting, entertaining elements along the way come to precious little in the end. This holds the book's rating down to two and a half stars.
