ORMALLY I FEEL PLEASANTLY MELLOW FOR SEVERAL days after one of my Nights Out, but the very next morning after MacGregor’s hasty exit I was still all aquiver with eagerness. I wanted very badly to find the photographer in the red cowboy boots and make a clean sweep of it. I am a tidy monster, and I do like to finish whatever I begin, and to know that someone was out there clumping around in those ridiculous shoes, carrying a camera that had seen far too much, made me anxious to follow those footprints and wrap up my two-part project.

Perhaps I had been too hasty with MacGregor; I should have given him a little more time and encouragement, and he would have told me everything. But it had seemed like something I could easily find by myself—when the Dark Passenger is driving, I am quite sure I can do anything. So far I have not been wrong, but it had put me in a bit of an awkward spot this time, and I had to find Mr. Boots on my own.

I knew from my earlier research that MacGregor did not have a social life beyond his occasional evening cruises. He belonged to a couple of business organizations, which was to be expected from a realtor, but I had not discovered anyone in particular that he seemed to pal around with. I also knew he had no criminal record, so there was no file to pull and search for known associates. The court records on his divorce simply listed “irreconcilable differences” and left the rest to my imagination.

And there I was stuck; MacGregor had been a classic loner, and in all my careful study of him I had never seen an indication that he had any friends, companions, dates, mates, or cronies. No poker night with the boys—no boys at all, except for the young ones. No church group, no Elks, no neighborhood bar, no weekly square-dancing society—which might have explained the boots—no nothing, except the photographs with those stupid pointed red toes sticking out.

So who was Cowboy Bob, and how did I find him?

There was really only one place I could go for an answer, and that would have to be soon, before someone noticed that MacGregor was missing. In the distance I heard thunder rumble, and I glanced at the wall clock with surprise. Sure enough, it was 2:15, time for the daily afternoon storm. I had moped all the way through my lunch hour, very unlike me.

Still, the storm would once again give me a little cover, and I could stop for something to eat on the way back. So with my immediate future neatly and pleasantly planned, I headed out to the parking lot, got into my car, and drove south.

The rain had started by the time I got to Matheson Hammock, and so once again I pulled on my sporty yellow foul-weather gear and jogged down the path to MacGregor’s boat.

I picked the lock again quite easily and slipped inside the cabin. During my first visit to the boat, I had been looking for signs that MacGregor was a pedophile. Now I was trying to find something a little bit more subtle, some small clue to the identity of MacGregor’s photographer friend.

Since I had to start somewhere, I went back down to the sleeping area. I opened the drawer with the false bottom and flipped through the pictures again. This time I checked the back as well as the front. Digital photography has made sleuthing a great deal more difficult, and there were no marks of any kind on the pictures and no empty film packets with traceable serial numbers, either. Any clod in the world could simply download the pictures to his hard drive and print them out at will, even someone with such hideous taste in footgear. It didn’t seem fair: Weren’t computers supposed to makes things easier?

I closed the drawer and searched through the rest of the area, but there was nothing that I hadn’t seen before. Somewhat discouraged, I went back upstairs to the main cabin. There were several drawers there, too, and I flipped through them. Videotapes, action figures, the duct tape—all things I had already noticed, and none of them would tell me anything. I pulled the stack of duct tape out, thinking, perhaps, that there was no sense in letting it go to waste. Idly, I turned over the bottom roll.

And there it was.

It really is better to be lucky than to be good. In a million years I could not have hoped for something this good. Stuck to the bottom of the duct-tape roll was a small scrap of paper, and written on the paper was, “Reiker,” and under that a telephone number.

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.

There really seemed nothing for me to do except bluff my way through: find out who was following me and why, and then convince them it was a silly way to waste time. I put on my very best Official Greeting face, got out of my car, and stepped briskly up to the Taurus. The window rolled down and the always angry face of Sergeant Doakes looked out at me, like an idol for some wicked god, carved from a piece of dark wood.

“Why you leaving work in the middle of the day so much lately?” he asked me. His voice had no real expression in it but still managed to give the impression that whatever I said would be a lie and he would like to hurt me for it.

“Why, Sergeant Doakes!” I said cheerfully. “What an amazing coincidence. What are you doing here?”

“You got something to do more important than your job?” he said. He really seemed uninterested in maintaining any sort of flow in the conversation, so I shrugged. When faced with people who have very limited conversational skills and no apparent desire to cultivate any, it’s always easier simply to go along.

“I, um—I had some personal things to take care of,” I said. Very weak, I agree, but Doakes displayed an unnerving habit of asking the most awkward questions, and with such an understated viciousness, that I found it hard enough not to stutter, let alone come up with something clever.

He looked at me for several endless seconds, the way a starving pit bull looks at raw meat. “Personal things,” he said without blinking. It sounded even stupider when he repeated it.

“That’s right,” I said.

“Your dentist is over in the Gables,” he said.

“Well—”

“Your doctor, too, over on Alameda. Got no lawyer, sister still at work,” he said. “What kind of personal things did I leave out?”

“Actually, um, I, I—” I said, and I was amazed to hear myself stammer, but nothing else came out, and Doakes just looked at me as though he was begging me to make a run for it so he could practice his wing shot.

“Funny,” he said at last, “I got personal things to do out here, too.”

“Really?” I said, relieved to find that my mouth was once again capable of forming human speech. “And what would that be, Sergeant?”

It was the first time I had ever seen him smile, and I have to say that I would have greatly preferred it if he had simply jumped out of the car and bitten me. “I’m watching YOU,” he said. He gave me a moment to admire the high gloss of his teeth, and then the window rolled up and he vanished behind the tinted glass like the Cheshire cat.
