always in the air. He was also getting used to the dark faces of the Maoris in the streets, but he couldnât get his mind free of Rita and Palfreyâs warning.
He was driven out of town, towards Taupo, then off the road where a sign read: âTrout Poolsâ.
The private road was narrow. It was broad daylight, and warm but not overpowering. The colouring of the trees was beautiful. At the end of the road they came to a small log hut, where two or three men stood about.
Palfrey was there.
They walked very quietly, until they came to a pool of crystal-clear water which reflected the perfect blue of the sky, and reflected the tops of trees â reflected their faces, too, as they looked down into it. Thirty or forty fully grown rainbow trout swam about lazily. The picture was so different from anything Banister had seen before that he felt tension easing. He watched the trout swimming in their endless circles.
Palfrey brought him back to the present, with a stab.
âTheyâre going to introduce the killer fish soon.â
âKiller? â
Palfreyâs look said: âYou know what I mean.â
Another man came carrying a large galvanised bucket. He had a long untidy moustache and looked miserable; melancholy. He stood watching the trout for a moment, then shrugged and tipped the bucket up and poured its contents into the pool.
The fish already there began to thrash the water and turn and dart and swerve, as if anxious to get away from some unknown threat. One fish joined them, sliding with the stream of water out of the bucket. The man with the moustache stood looking down; other men appeared. Banister heard the whirl of a cine camera, but didnât glance round. The pool was a reflection of the sky and the sunâs brightness, and the spotted fish gave it beauty as they twisted and turned, gliding more slowly now as their alarm subsided.
There was a flash.
It wasnât bright or blinding, nothing like the flashes which Banister had seen before â but a moment later, one of the fish floated to the surface.
Banister felt his hands clenching unseen steel.
There was another flash; another fish rose.
âItâs murder, thatâs what it is, plain murder!â growled the man who had brought the bucket with the killer fish. âIt oughtnât to be allowed. I wonât do it again, Iââ
He turned and flung himself along the path leading away from the pool; they could hear the thud of his footsteps.
The camera went on whirring.
Fish after fish floated to the surface.
Ten minutes later, the surface of the pool was covered with the dead fish, their mouths and eyes open. The sun shone down upon them, and the water of the pool was as clear as it had been â rippling as one, the killer, fish swam round and round, looking for fresh victims.
âAll those had been treated with what we hoped would be a form of insulation,â Palfrey said. âIt didnât work.â
Banister made himself speak: âWho handles the killer fish?â
âAnyone â with a net and bucket. Thereâs no contact. The people who own the pools, which are spawning grounds of course, discovered what was happening. There were several killer fish. They were isolated, and they had no effect on one another, but killed any other fish with whom they came in contact. Mike â my driver â knew what we were looking for, and heard of this. Thatâs one reason why we concentrated. We found Rita, and evidence of insulated fish â insulated or immune. But thereâs nothing to suggest any peculiar qualities in the uranium ore anywhere near Rotorua. Weâre wondering if itâs a different form of phenomenon â there are sting rays and electric fish which can kill. But troutââ
He began to twist a few strands of hair round his forefinger.
âHas anything else been found?â
âNot a thing.â Palfrey patted the strands of hair
