Of course there was no guarantee that Reiker was the Red Ranger, or even that he was a human being. It could well be the name of a marine plumbing contractor. But in any case, it was far more of a starting place than I’d had, and I needed to get off the boat before the storm stopped. I stuck the paper inside my pocket, buttoned up my rain slicker, and snuck off the boat and onto the footpath again.

Perhaps I was feeling so happily mellow from the aftereffects of my evening out with MacGregor, but as I drove home I found myself humming a catchy little Philip Glass tune from 1000 Airplanes on the Roof. The key to a happy life is to have accomplishments to be proud of and purpose to look forward to, and at the moment I had both. How wonderful it was to be me.

My good mood lasted only as far as the traffic circle where Old Cutler blends into LeJeune, and then a routine glance in my rearview mirror froze the music on my lips.

Behind me, practically nosing into my backseat, was a maroon Ford Taurus. It looked very much like the sort of car the Miami-Dade Police Department maintained in large numbers for the use of plainclothes personnel.

I did not see how this could possibly be a good thing. A patrol car might follow for no real reason, but someone in a motor-pool car would have some kind of purpose, and it looked like that purpose was to make me aware I was being followed. If so, it was working perfectly. I could not see through the glare of the windshield to know who was driving the other car, but it suddenly seemed very important to know just how long the car had been following me, who was driving, and how much the driver had seen.

I turned down a small side street, pulled over, and parked, and the Taurus parked right behind me. For a moment, nothing happened; we both sat there in our cars, waiting. Was I going to be arrested? If someone had followed me from the marina, it could be a very bad thing for Dashing Dexter. Sooner or later, MacGregor’s absence would be noticed, and even the most routine investigation would reveal his boat. Someone would go to see if it was there, and then the fact that Dexter had been there in the middle of the day might seem very significant.

It’s little things like this that make for successful police work. Cops look for these funny coincidences, and when they find them they can get very serious with the person who is in too many interesting places by mere happenstance. Even if that person has a police ID and an amazingly charming fake smile.
