Not honest guilt, of course. She's trolling for fear of discovery, she's on the prowl for righteous anger. Newly reawakened, she swims through a faint cauldron of secondhand emotions. The water's tainted with a dozen kinds of fear, of anger, with the loathing of self and others. A darker center roils beneath the surface of each dark body. There's also excitement of a sort, the initial thrill of the chase decaying exponentially down to rote boredom. Sexual stirrings. Other, fainter feelings she can't identify.

She's never forgotten why she resisted fine-tuning back at Channer, even after all the others had gone over. Now, though, she remembers why she found it so seductive when she finally gave in: in that endless welter of feelings, you always lost track of which ones were yours...

It's not quite the same here on the Ridge, unfortunately. Not that the physics or the neurology have changed. Not that anyone else has. It's Lenie Clarke that's different now. Victim and vendetta have faded over the years, black and white have bled together into a million indistinguishable shades of gray. Her psyche has diverged from the rifter norm, it no longer blends safely into that background. The guilt alone is so strong that she can't imagine it arising from anyone but her.

She stays the course, though. She keeps hunting, though her senses are dulled. Somewhere off in the diffracted distance, Ken Lubin is doing the same. He's probably a lot better at it than she is. He's had training in this kind of thing. He's had years of experience.

Something tickles the side of her mind. Some distant voice shouts through the clouds in her head. She realizes that she's been sensing it for some time, but its volume has crept up so gradually that it hasn't registered until now. Now it's unmistakable: threat and exclamation and excitement, at the very limit of her range. Two rifters cross her path, heading south, legs pumping. Clarke's jaw is buzzing with vocoded voices; in her reverie, she's missed those too.

"Almost missed it completely," one of them says. "It was tucked in under—"

"Got another one," A second voice breaks in. "Res-A."

One look and Clarke knows she would have missed it.

It's a standard demolition charge, planted in the shadow of an overhanging ledge. Clarke floats upside down and lays her head against the hull to look along the space beneath; she sees a hemispherical silhouette, shaded by the ledge, backlit by the diffuse murky glow of the water behind.

"Jesus," she buzzes, "How did you find the damn thing?"

"Sonar caught it."

With typical rifter discipline, the searchers have abandoned their transects and accreted around the find. Lubin hasn't sent them back; there's an obvious reason why he'd want them all here with the murder weapon. Clarke tunes and concentrates:
