THE BUILDING AT 495 East Pike was less than a mile away from Harborview. It was a large, two-story brick structure with a chiropractor on the second floor and a Mailbox Worldwide shipping franchise on the first.

It was before the lunch hour, and the Mailbox office was quiet. Between the painted words on the windows, I could see a young woman behind the counter, sealing boxes with strapping tape.

A man walked in and headed for the bank of golden-doored boxes on the side wall. I followed him inside and pretended to be listening intently to my phone while finding Box 1701, high on the right side. I watched as the man used a short silver key with a circular head to open his box. Dono had a similar silver key on the big key ring in my pocket.

When the woman carried the cardboard box into the back, I walked over to the wall and opened Box 1701 with Dono’s key. It was crammed full of envelopes and postcards. A lucky spin for me that Dono hadn’t picked up his mail in a while. I stuffed the stack of mail into my jacket and left. I sat in the driver’s seat of the Charger to leaf through J. T. Callahan’s correspondence.

Most of the stack turned out to be advertisements. Tool shops obviously liked Callahan. The more personal items included a bank statement, a couple of letters from workman’s associations, and an envelope from Western Maritime.

I opened the envelope. It was a receipt correction and a letter, apologizing to Mr. Callahan for the incorrect pricing of his purchases in February and hoping that he was enjoying them to the full. I looked at the receipt. A Lowrance HD Chartplotter, a Garmin VHF radio, and other equipment. Over four grand of new electronics in all.

Which confirmed that Dono had acquired a boat, and recently. But it didn’t tell me where it was.

I checked the bank statement. It was short. The balance was just under twenty thousand. There had been automated withdrawals for his mailbox, for the car insurance on the Lincoln, and for Altamont Garage, which I guessed was where he kept the Lincoln.

And one more withdrawal, for something called BLUERIDGE MOOR LLC. I took out my phone and searched for the name. There was a Blue Ridge Marina, a couple miles north of the big public piers at Shilshole Bay in Seattle.

Hot damn.

AT FIRST GLANCE THE marina didn’t look like much. Just a row of six or seven short docks separated from Puget Sound by a breakwater. Maybe two hundred slips in all. But the resident vessels were upmarket, mostly oceanworthy sailboats and tall cruising yachts. I saw a lot of varnished teak and shiny brass fittings that managed to gleam even on this overcast day. It was Monday, and the docks were empty of people.

Each floating dock had its own entrance door, made of flat steel mesh with side extensions and razor wire on the top to keep the riffraff from climbing around to the ramp.

I knew from Ganz’s guy at the DMV what I was looking for. A twenty-two-foot gray Stingray speedboat. All the boats near that size were parked in the slips closest to shore, because they had shallower drafts than their bigger cousins. I walked down the row of docks, looking at them. Most were white, with a few blues and blacks. Only one was gray.

The lock on the steel gate was a heavy mechanical combination type. Six punch buttons marked with letters of the alphabet, A through F. I had a pry bar from the truck under my coat, but a quick glance at the lock told me I wouldn’t need it.

Four of the six buttons were shiny from repeated use. Each button can only be used once in a mechanical lock, since each corresponds to a separate tumbler inside. Four buttons, twenty-four possible combinations. When I put a little tension on the door handle and pressed gently on each button, I could tell by touch that button C was first in the sequence, because its tumbler wasn’t providing as much resistance. Eight possible sequences left. By trial and error, I had the gate open in forty more seconds.

It had been a long time since I’d greased a lock with just my hands. Score one for the riffraff. I walked down the dock to the boat.

The Stingray was a sport boat, built for zipping between islands on day trips or dragging water-skiers behind it. About half of its length was the sleek bow section in front of its raked windshield. No name was painted on the stern. Nothing about the boat stood out as particularly unique. Even the gray paint was dull.

There was a buff-colored canvas cover over the entire cockpit and engine, to keep both shielded from the weather. The cover was fastened in place with hooks and elastic cord every foot or two around the edges of the hull. I unhooked the cord and pulled the canvas back until I could fold it out of the way onto the foredeck.

The engine was a monster, a black Mercury 300-horse. Dono had covered it with a rubber muffling cowl to help keep the noise from rattling his eardrums loose. There were two red five-gallon jerry jugs tied to the inside of the stern, spare fuel tanks that could be connected with a hose directly to the thirsty engine.

The whole package wasn’t as fast or as flashy as a go-fast boat, the kind made famous by drug smugglers around the world. But I would lay money that the deep spearhead of its hull could manage forty knots an hour on a flat sea without straining. Add in the extra fuel tanks and the boat might have a range of a hundred miles or more.

Two short, narrow doors separated the cockpit from the cabin. They were locked. One of the little gold keys attached to the chunk of red driftwood matched.

The cabin had a single cushioned seat on each side and room forward of the seats to sleep two people on a thin sectional mattress. The mattress pieces were shaped to fit the sloping V of the boat’s bow. Under the mattress was a big trapezoid area for storage. Bolted to the cabin wall, on a swing arm so it could be pulled out and seen from the cockpit, was the Chartplotter depth sounder I’d seen listed on the Western Maritime receipt mailed to J. T. Callahan.

I pulled the seat cushions and mattress pieces into the cockpit and searched the cabin.

The storage area was divided by wooden slats into sections. Most of what I found inside was normal pleasure-boat stuff. Lines and life vests and foul-weather gear.

There was a set of scuba gear. One tank and a regulator. A buoyancy-control vest and a weight belt. And a wet suit that looked like it would fit Dono. The set looked used but in good shape.

I sniffed at the wet suit. It had been rinsed clean, but rinsing never fully got the saltwater smell out. I looked closely at the tank. There was a little salt rime in the grooves of the valve handles.

I was sure the gear had been used sometime recently. A week ago, maybe. No longer than a month.

Stranger and stranger. Dono hadn’t bought the speedboat just to motor around the sound, and he didn’t dive for the fun of it either. At least not when I’d been with him. I wasn’t even aware that he knew how.

The ivory paint on the wooden bottom of the storage space was fresher than the shade on the sides. I knocked the wood, and it echoed. I felt around the edge. On the aft side, there was a small half circle cut in the wood, just out of sight.

I put my finger in the little hole and pulled up, revealing a shallow space along the V of the hull. A bolt-action Remington 30.06 hunting rifle was secured with rubber ties on the starboard side. There was a slim stainless-steel case that I opened to find an older Beretta handgun and boxes of cartridges for it and the rifle.

The Remington and the Beretta were safety measures, just like the life jackets. If Dono had had to choose between the two, he’d have taken the guns.

I climbed out of the cabin, back into the cockpit. There were watertight compartments along the sides of the cockpit seats. I opened them with the same key as for the cabin.

The forward compartment held the VHF radio and thick books of nautical charts. I pulled out the books. They were a set of three, covering the West Coast from southern Oregon up through Washington and the San Juan Islands and farther into British Columbia, as far north as Queen Charlotte Sound.

An idea struck me, and I turned on the VHF. The monotone voice of NOAA Weather Radio came out. NOAA was the coastal marine forecast, broadcasting out of Port Angeles on a continuous loop.

Like a car radio, the VHF had a row of buttons for preset channels. I hit the next button, and there was the same recorded voice again, much fainter. I listened until it identified itself as being for the Bellingham area, just an hour south of the Canadian border. The third channel gave me only garbled static.

Tucked under the VHF was a paper booklet that looked like it had come with the radio, covering basic radio protocol and a long list of channels and their uses for the Northwest coast. The frequency shown on the radio’s display for the third channel matched the Weatheradio Canada broadcast out of Vancouver. The fourth, fifth, and sixth buttons were not preset, showing the end of the VHF frequency range.

North, then. Dono had taken the boat north, and not too far or he’d have needed the weather station for farther up the Canadian coast.

Fast boat. Longish range. Maybe up as far as Canada. Had Dono been smuggling something?

Smuggling wasn’t his usual racket. Moving contraband was Hollis Brant’s line of work. And why Dono’s sudden interest in scuba? I put everything back in the storage area and locked up the cabin and the compartments.

The sun was low on the horizon. Its light bounced off the calm sound, making a glowing white rift in the wide expanse of steel-colored water on either side. Across the water was the dark green line of Bainbridge Island, and far beyond that the jagged white-gray of the Olympics. The mountains here looked different from the ones in Afghanistan. Gentler. The Afghan ranges were like cliffs, shaped into crude knife edges at the top.

I checked my watch: 1815. Davey would be at the Morgen soon.

I took Dono’s key and turned it in the ignition. The big Mercury gave a high roar and then settled back into a bubbling growl. I’d drive the boat up to Hollis’s slip at Shilshole and ask him to look it over. His practiced eye might spot something about the gray Stingray that I’d missed.

For a moment I was tempted to let my reunion with Davey slide. But I was coming up dry on learning what action had been keeping Dono busy lately. Finding his boat had added more questions than it had answered.

Maybe blowing off some steam would do me good. Have a beer and a laugh before I found myself head-butting a wall.
