I imagine Commanding Voice ("FREEZE!") would be awesome for any type of adept cop, too.
I'd probably go with straight-up Astral Perception instead of Empathic Reading for a detective, however. Being able to scan over astral signatures and identify them at a later time would be phenomenal. It also opens the door to some metamagics you'll definitely want, like Psychometry. Other great metamagic techniques to take with those three free levels include Divination and Centering (since they'll help both of the other two in addition to your Athletics and Stealth skills). I used all of them to great effect with a paranormal investigator character I've played in the past.
You can capture some of that noir flair with your geasa and Centering skills, too. Condition Geas: Smoking and Centering Linked Skill: Inner Monolgues would be great, I'd imagine.
I can't bring myself to encourage the use of Kinesics, however. <twitch>
You might want to consider some edges along those lines, though. Two that would be really great for this type of character include Friendly Face and Good Looking & Knows It or a variant thereof (like "Trustworthy Personality" or "Oozes With Confidence" as examples of what I'm talking about). If you plan on having a bunch of contacts you use to muscle information out of, Good Reputation would be fantastic, too.
Beyond that, a maxed out Police Procedures, Tracking (Tailing), and Forensics knowledge skills would be invaluable.
When selecting your skills (which should be an emphasis for this type of character), don't forget some easily forgotten ones like Electronics, Electronics B/R, and Lockpicking (or just get an Autopick if you prefer -- better investment, really). You're basically a "good guy" thief, afterall.
