M.A.C. COPS ALWAYS COME IN TWOS. One will knock on the door, but a pair will come in, a duet on hand in case you get rowdy. One uniform drives the squad car, the other answers the radio. One plain-clothes dick asks the questions, the other takes the notes. Sometimes I think the only time they go solo is to the dentist. Or to bed. Or to kill themselves. I went out into the outer office where a client had been waiting for ten minutes for me to wrap up a phone call. I nodded to him, but the six-footer was already on his feet, brown shoes, brown suit, brown eyes, brown hair. It was a relief his name wasn’t Brown. I said, “I can see you now, Mr. Hanson.” At her reception desk to one side of my inner-office door, Velda—a raven-haired vision in a white blouse and black skirt—was giving me a faintly amused look that said she had made him, too. Mr. Hanson nodded back. There was no nervous smile, no anxiety in his manner at all. Generally, anybody needing a private investigator is not at ease.
