Two ex-cops are currently turning out mysteries centering on the LAPD’s Hollywood Division: Joe Wambaugh, who left the job fairly early after establishing the genre of gutsy, raucous police procedurals, and Connie Dial, who retired as commanding officer of the Hollywood Division after 27 years, including patrol, undercover, and narcotics work. Wambaugh gives readers a totally wild ride, often veering off into tangentially related war stories and cop humor, careening back into plot limits just in time. Dial’s ride (this is her third novel) is much more controlled when it comes to obeying conventional limits with plot and characters…. As with Wambaugh, the great thing about Dial is that readers know her take on the LAPD and the craziness of Hollywood crime is based on long reflection.
