"Every living thing emits a characteristic pattern of electrical nerve impulses. We have ways of recording those impulses, and we have had you and Cargill under observation for a long time. We've had plenty of opportunity to key this Toy to Cargill's pattern." On his palm the curled thing stirred, spread wings. A fledgling bird lay there, small soft body throbbing slightly. Half-hidden in a ruff of metallic feathers I glimpsed a grimly elongated beak. The pinions were feathered with delicate down less than a quarter of an inch long. They beat with delicate insistence against the Toymaker's prisoning fingers. "This is not dangerous to you. Press here"--he showed me--"and if Race Cargill is within a certain distance--and it is up to you to be _within_ that distance--it will find him, and kill him. Unerringly, inescapably, untraceably. We will not tell you the critical distance. And we will give you three days." He checked my startled exclamation with a gesture. "Of course this is a test. Within the hour Cargill will receive a warning. We want no incompetents who must be helped too much! Nor do we want cowards! If you fail, or release the bird at a distance too great, or evade the test"--the green inhuman malice in his eyes made me sweat--"we have made another bird." By now my brain was swimming, but I thought I understood the complex inhuman logic involved. "The other bird is keyed to me?" With slow contempt Evarin shook his head. "You? You are used to danger and fond of a gamble. Nothing so simple! We have given you three days. If, within that time, the bird you carry has not killed, the other bird will fly. And it will kill. Rakhal, you have a wife." Yes, Rakhal had a wife. They could threaten Rakhal's wife. And his wife was my sister Juli. Everything after that was anticlimax. Of course I had to drink with Evarin, the elaborate formal ritual without which no bargain on Wolf is concluded. He entertained me with gory and technical descriptions of the way in which the birds, and other of his hellish Toys, did their killing, and worse tasks. Miellyn danced into the room and upset the exquisite solemnity of the wine-ritual by perching on my knee, stealing a sip from my cup, and pouting prettily when I paid her less attention than she thought she merited. I didn't dare pay much attention, even when she whispered, with the deliberate and thorough wantonness of a Dry-town woman of high-caste who has flung aside her fetters, something about a rendezvous at the Three Rainbows.
