Researching a novel can involve more than history books, archives, and the other usual resources for honing details of terrain, lifestyle, time. What about describing emotions, personality, and the intangible nuances?
The subject came to mind in riding along with a police officer on patrol. I asked the officer what resources she found helpful and that led to a conversation about lying. One book she found very useful, the police officer said, was Spy the Lie by Philip Houston, Michael Floyd, and Susan Carnicero with Don Tennant. The authors are former CIA officers who use a methodology developed by Houston to detect deception in the counterterrorism and criminal investigation realms. They show how these techniques can be applied in our daily lives.
