The novel is notable for an appearance by LAPD detective Harry Bosch, on page 9:
- Ahead I could see my lieutenant walking toward the parking lot, where he shook hands with a curly-headed, mustachioed guy who used to work at RHD. Stobaugh couldn't be trying to get Harry Bosch transferred back to Robbery-Homicide, not after that case he'd screwed up.
- Or maybe, my voice proposed, Bosch can fill the spot on Stobaugh's team you'll be vacating if you don't get your act together.
Bosch had in fact returned to the RHD Open-Unsolved Unit in 2005, and eventually transferred back to the RHD Homicide Special Unit in 2007.
