Erigeron has sent his affinity-bonded ferret into the office building, scouting out the interior. The jet-black creature puts Laurus in mind of a snake with paws, but it does possess an astonishing ability to wriggle through the smallest of gaps as if its bones were flexible.

According to Erigeron, the only humans inside are the girl and a young boy who seems to be injured. He also says there is some kind of machine in the room, powered by a photosynthetic membrane hanging under the skylight. Laurus is regretting that each affinity bond is unique and impregnable. He would like to have seen for himself; all Ryker can offer him is blurred outlines through algae-crusted skylights.

The conclusion he has grudgingly arrived at is that the inventor of these candy buds is elsewhere. He could wait, mount a surveillance operation to see if the inventor shows up. But he is too near now to adopt a circumspect approach, every delay could mean someone else learning about candy buds. If this knowledge were to go elsewhere his own power would be lost. This is a matter of survival now.

Very well, the girl will simply have to provide him with the inventor's location. There are methods available for guaranteeing truth.

«Go,» he tells Erigeron.

The enforcer squad penetrates the office building with deceptive efficiency; their sleek hounds racing ahead of them, sensors alert for booby traps. Laurus feels an excitement that has been missing for decades as he watches the armour-clad figures disappear into the gloomy interior.

Erigeron emerges two minutes later and pushes up his helmet visor to reveal a bleak angular face. «All secure, Mr Laurus. We've got 'em cornered for you.»

Laurus strides forwards, eagerness firing his blood.

The room's light comes from a single soot-stained skylight high above. A pile of cushions and dirty blankets makes up a sleeping nest in one corner. There's an oven built out of loose bricks, small broken branches crackling inside, casting a dull ruby glow. The feral squalor of the den is more or less what Laurus expected, except for the books. There are hundreds of them, tall stacks of mouldering paperbacks leaning at precarious angles. Those at the bottom of the pile have already decayed beyond rescue, their pages agglutinating into a single pulp brickette.

Laurus has a collection of books at his mansion, leather-bound classics imported from Kulu. He knows of no one else on Tropicana who has books. Everyone else uses space chips.

The girl is crouched beside an ancient hospital commode, her arms thrown protectively around a small boy with greasy red hair, no more than seven or eight. A yellowing bandage is wrapped round his head, covering his eyes. Cheesy tears are leaking from the linen, crusting on his cheeks. His legs have wasted away, now little more than a layer of pale skin stretched over the bones, the waxy surface rucked by tightly knotted blue veins.

Laurus glances round at the enforcer squad. Their plasma carbines are trained on the two frightened children, hounds quiver at the ready. The girl's wide green eyes are moist from barely contained tears. Shame tweaks him. «That's enough,» he says. «Erigeron, you stay. The rest of you, leave us now.»
