As I approached another intersection, two radiant red eyes, low in front of me, brought me to a stop. The fairy light teased fitfully across the shape before me, but then revealed a rat sitting precisely where the two beams joined.

I am not afraid of rats. Neither am I so tolerant that I would welcome a swarm of them into my home in a spirit of interspecies brotherhood.

The rat was paralyzed by the sight of me looming over it. If I advanced another step, it had three routes by which it could flee to safety.

In moments of stress, my imagination can be as ornate as a carousel of grotesque beasts, standing on end like a Ferris wheel, spinning like a coin, casting off kaleidoscopic visions of ludicrous fates and droll deaths.

As I confronted the rat, I saw in my mind’s eye a scenario in which I startled the rodent, whereupon it raced toward me in a panic, slipped under a leg of my jeans, squirmed up my calf, squeaked behind my knee, wriggled along my thigh, and decided to establish a nest between my buttocks. Through all of this, I would be windmilling my arms and hopping on one foot until I hopped off the beam and, with the hapless rodent snugged between my cheeks, plunged toward the sea just in time to crash into the searchers’ boat, smashing a hole in the bottom with my face, thereupon breaking my neck and drowning.

You might think that I have earned the name Odd Thomas, but it has been mine since birth.

The racket of the outboard sawed through the support posts, echoing and re-echoing until it seemed that legions of lumberjacks were at work, intent on felling the entire structure.

When I took a step toward the rat, the rat did not relent. As I had nothing better to do, I took another step, then halted because the noise of the outboard abruptly became explosive.

I dared to look down. An inflatable dinghy passed below, wet black rubber glossy under the floodlamps.

The hulk in the Hawaiian shirt sat on the sternmost of two thwarts, one hand on the steering arm of the engine. He piloted the boat with expertise, weaving at speed between the concrete columns, as if late for a luau.

On the longer port and starboard inflation compartments that formed the rounded bulwarks of the craft, in yellow letters, were the words MAGIC BEACH/HARBOR DEPT. The dinghy must have been tied up to the pier; the giant had boldly stolen it to search for me.

Yet he never looked up between the floodlamps as he passed under me. If the dinghy doubled as a search-and-rescue craft, waterproof flashlights would be stowed aboard; but the hulk wasn’t using one.

The small craft disappeared among the staggered rows of columns. The engine noise gradually diminished. The ripples and dimples of the dinghy’s modest wake were smoothed away by the self-ironing sea.

I had expected to see three men in the boat. I wondered where the dead-eyed redheads had gone.

The other rat had vanished, too, but not up a leg of my blue jeans.

Exhibiting balletic poise, foot in front of foot, I stepped into the junction of beams, which the trembling rodent had once occupied. I meant to continue shoreward, but I stopped.

Now that the blond giant was under the pier, between me and the beach, I was not confident of continuing in that direction.

The mood had changed. An overwhelming sense of peril, of being in the mortal trajectory of a bullet, had propelled me into frantic flight. Now death seemed no less possible than it had before the passage of the dinghy, but less imminent.

The moment felt dangerous rather than perilous, characterized by uncertainty and by the tyranny of chance. If a bullet was coming, I now had hope of dodging it, though only if I made the right moves.

I looked north, east, south along the horizontal beams. West, over my shoulder. Down into floodlit tides. I looked up toward the underside of the pier deck, where the dancing sea translated itself into phrases of half-light that swelled and fluttered and shrank and swelled in an eerie choreography through geometric beams and braces.

I felt as indecisive as the feckless mob in The Second Part of King Henry the Sixth, Act 4, when they vacillate repeatedly between swearing loyalty to the grotesque Cade, then to the rightful king.

Shakespeare again. Once you let him into your head, he takes up tenancy and will not leave.

The sound of the outboard engine had been waning. Abruptly it cut out altogether.

Briefly the silence seemed perfect. Then the wordless whispering and the soft idiot chuckling of the sea began to echo off surrounding surfaces.

In the brief period since the dinghy had passed under me, it could not have traveled all the way to the beach. It had probably gone little more than half that distance.

The hulk at the tiller would not surrender steering to the sea and let it pinball the dinghy from post to post. He must have somehow tied up to one of the concrete columns.

He would not have moored the dinghy unless he intended to disembark from it. Already he must be climbing into the pier support structure ahead of me.

Certain that I knew where the redheaded gunmen were, I looked over my shoulder, through the labyrinth of posts and beams to the west. They were not yet in sight.

One in front of me. Two behind. The jaws of a nutcracker.

WHILE I DITHERED AT THE INTERSECTION OF support beams, a pale form loomed out of the south, to my right.

Because occasionally spirits manifest suddenly, unexpectedly, with no regard for my nerves, I don’t startle easily. I swayed on the timber but did not plummet from it.

My visitor proved to be Boo, good dog and former mascot of St. Bartholomew’s Abbey in the California Sierra.

He could be seen by no one but me, and no touch but mine could detect any substance to him. Yet to my eyes at least, the shimmering reflections sprayed up by the rolling sea played off his flanks and across his face, as if he were as solid as I was.

Although he could have appeared in midair, he walked the crossbeam toward me, like the ghost of Hamlet’s father approaching the doomed prince on the platform before the castle.

Well, no. Boo had a tail, soft fur, and a friendly smile. Hamlet’s father had none of that, although Hollywood would no doubt eventually give him all three in some misguided adaptation.

I hoped that the Hamlet comparison was inappropriate in other ways. At the end of that play, the stage is littered with dead bodies.

Boo stopped when he knew that I had seen him, cocked his head, and wagged his tail. Suddenly facing away from me without having turned around, he padded south, paused, glanced back at me, and then continued.

Even if I had not watched a lot of old episodes of Lassie, I understood the dead well enough to know that I was expected to follow my dog. I took some small pride that, unlike young Timmy in the TV show, I didn’t need to be barked into obedience.

The blond hulk had not appeared in the east, nor the redheads in the west, so I hurried, if gingerly, after the ghostly shepherd, who led me toward the south side of the pier.

At the end of the timber path, I came to a large railed landing that served two flights of ascending stairs, one to the left, one to the right. The landing might have been a staging platform for workers of one kind or another.

When Boo climbed the stairs to the left, I went after him. The flight was short, and at the top lay a four-foot-wide railed catwalk.

The underside of the pier deck hung little more than one foot above my head. In this high corridor, where only a storm wind could have stirred the air, the stink of creosote thickened.

Darkness pooled deeper here than elsewhere. Nevertheless, the quivering marbled reflections, ever-changing on the ceiling, revealed electrical conduits, junction boxes, and copper pipes that must have been water lines.
