Early in the 1990s, I flew alone in a dandelion-yellow, single-engine, 180-horsepower Piper Cherokee from Westchester County Airport in New York westward to the Rocky Mountains, landing and refuelling a good many times in middle-sized cities and towns along the way.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.

Yes. I did more research than I ever wanted to and saw some things I wish I didn't. I went on ride-alongs, spent time with Homicide, Cold Case, and SVU detectives, hung out in subways learning how to spot pervs and pick-pockets, viewed an autopsy, went to a police firing range, and witnessed court cases and I read, read, read.
