Before long I can see the glitter of water ahead of us. I lean forward, craning my head between the two front seats, to see the satnav map Argent’s brought up on the co-pilot’s main display station. Yep, the water ahead is the Columbia, just like I guessed. According to the little point of light that’s the Merlin, we’re ten klicks to the east of Pillar Rock, passing over the town of Skamokawa. We buzz over the town—a small, spotless-looking community—and Raven banks the plane right, westward. Judging by what I think is a radar altimeter, we’re down to five hundred meters or so. Speed’s cut back too, down to about three hundred klicks.
