I would tell Deborah that I had taken the sudden opportunity of a no-Doakes zone and gone dashing into the darkness with a Need and a Knife as the last few fingers of her boyfriend trickled away into a trash heap? Somehow, even with my inner cheerleaders insisting that it would be all right, I didn’t think she would go for it. It had the feel of something final in my relationship with my sister, a small lapse in judgment, perhaps, but one she would find a bit hard to forgive, and even though I am not capable of feeling actual love, I did want to keep Debs relatively happy with me.

And so once again I was left with virtuous patience and a feeling of long-suffering rectitude. Dour Dutiful Dexter. It will come, I told my other self. Sooner or later, it will come. Has to come; it will not wait forever, but this must come first. And there was some grumbling, of course, because it had not come in far too long, but I soothed the growls, rattled the bars with false good cheer one time, and pulled out my cell phone.

I dialed the number Doakes had given me. After a moment there was a tone, and then nothing, just a faint hiss. I punched in the long access code, heard a click, and then a neutral female voice said, Number. I gave the voice Doakes’s cell number. There was a pause, and then it read me some coordinates; I hurriedly scribbled them down on the pad. The voice paused, and then added, Moving due west, 65 miles per hour. The line went dead.

I never claimed to be an expert navigator, but I do have a small GPS unit that I use on my boat. It comes in handy for marking good fishing spots. So I managed to put in the coordinates without bumping my head or causing an explosion. The unit Doakes had given me was a step up from mine and had a map on the screen. The coordinates on the map translated to Interstate 75, heading for Alligator Alley, the corridor to the west coast of Florida.

I was mildly surprised. Most of the territory between Miami and Naples is Everglades, swamp broken up by small patches of semidry land. It was filled with snakes, alligators, and Indian casinos, which did not seem at all like the kind of place to relax and enjoy a peaceful dismemberment. But the GPS could not lie, and supposedly neither could the voice on the phone. If the coordinates were wrong, it was Doakes’s doing, and he was lost anyway. I had no choice. I felt a little guilty about leaving the party without thanking my host, but I got into my car and headed for I-75.
