L.A. Requiem by Robert Crais is the 8th novel in the Elvis Cole/Joe Pike series. The author has a website where you can read an excerpt. I remember enjoying this book when I read it but have honestly forgotten all of it. I read it back when The Grandmother was in the hospital. Spending the nights there with her once I wasn't quite so worried, this book made a fine distraction. Along with HGtv's Design Star. I took my distractions where I could get them in those days.
from the back of the book:
The day starts like any other in L.A. The sun burns hot as the Santa Ana winds blow ash from mountain fires to coat the glittering city. But for private investigator Joe Pike, the city will never be the same again. His ex-lover, Karen Garcia, is dead, brutally murdered with a gun shot to the head.
Now Karen's powerful father calls on Pike and his partner, Elvis Cole, to keep an eye on the LAPD as they search for his daughter's killer - because in the luminous City of Angels, everyone has something to hide. But what starts as routine turns into a deadly game of cat-and-mouse. For a dark web of conspiracy threatens to destroy Pike and Cole's twelve-year friendship - if not their lives.
Kirkus Reviews calls it "a taut, suspenseful case". SFF.net likes it, opening this review saying, "If you don't buy and read this book, you ought to be shot." sfgate says, "in "L.A. Requiem" he's found his own voice and has made himself a contender."
