As the sentry in front of him seems to stare out at nothing, reading the information that marches across his vision, Lamentation Kane opens his mouth to say something — to make small-talk the way a real returning citizen of Archimedes would after a long time abroad, a citizen guilty of nothing worse than maybe having watched a few religious broadcasts on Arjuna — when he sees movement out of the corner of his eye. Inside the u-glass holding cell the young, brown-skinned woman lifts her arms. One of the armored guards lurches back from the table, half-falling, the other reaches out his gloved hand as though to restrain her, but his face has the hopeless, slack expression of a man who sees his own death. A moment later bluish flames run up her arms, blackening the sleeves of her loose dress, and then she vanishes in a flare of magnesium white light.

People are shrieking and diving away from the glass wall, which is now spiderwebbed with cracks. The light burns and flickers and the insides of the walls blacken with a crust of what Kane guesses must be human fat turning to ash.

A human explosion — nanobiotic thermal flare — that partially failed. That will be their conclusion. But of course, the architects of Kane’s mission didn’t want an actual explosion. They want a distraction.

The sentry in the guardpost polarizes the windows and locks up his booth. Before hurrying off to help the emergency personnel fight the blaze that is already leaking clouds of black smoke into the concourse, he thrusts Kane’s itinerary into his hand and waves him through, then locks off the transit point.

Lamentation Kane would be happy to move on, even if he were the innocent traveler he pretends to be. The smoke is terrible, with the disturbing, sweet smell of cooked meat.
