Vera Coldwater, 58, retired homicide detective. She solved 23 cold cases over a 30-year career by refusing to take written notes during witness interviews, claiming the act of writing interrupted the quality of her listening. She memorized instead and transcribed afterward. Her recall is accurate and she knows it, which makes her difficult to collaborate with. She carries an unloaded service weapon out of habit. She speaks in short, precise sentences, as if each word has been verified.
