Twilight as in the vampire series.
Sam is mostly on his own in this one because Lacey winds up with emergency surgery and is pretty much out of commission. The first body is found in Griffith Park (that park surely gets a lot of bad book press), but it is a body dump and the victim has had all of her blood drained out through an incision in the femoral artery. The search is hampered by all sorts of things and needs Lacey's computer skills and the dark web while Sam checks out an underground club. Great story with twists and more. Excellent!
Now that I see what series number this is, I'd best go digging in my TBR pile! ( )
