The creature across the room-Reith could not think of him as a man, stood quiet without a twitch to his features, just inconveniently too distant for a lurch and a lunge out of the closet.

Reith began to feel cramped. He shifted his position, producing a small sound.

In a cold sweat he pressed his eye to the crack. The Pnumekin stood absorbed in reverie. Reith willed him to approach, urged him closer, closer, closer ... A

thought came to disturb him: suppose the creature refused to heed a threat against his life? Perhaps it lacked the ability to feel fear ... The portal swung ajar; another Pnumekin entered: one of the passage-tenders. The two looked aside, ignoring each other. The newcomer spoke in a soft voice, as if musing aloud: "The delivery cannot be found. The passage and shaft have been scrutinized."

The tunnel monitor made no response. Silence, of an eerie dream-like quality, ensued.

The passage-tender spoke again. "He could not have passed us. Delivery was not made, or else he escaped by an adit unknown to us. These are the alternative possibilities."

The monitor spoke. "The information is noted. Transit control should be instituted at Ziad Level, Zud-Dan-Ziad, at Ferstan Node Six, at Lullil Node and at Foreverness Station."

"Such will be the situation."

A Pnume came into the chamber, using an aperture beyond Reith's range of vision.

The Pnumekin paid no heed, not so much as glancing aside. Reith studied the oddly jointed creature: the first Pnume he had seen, except for a darkling glimpse in the dungeons of Pera. It stood about the height of a man and within its voluminous black cloak seemed slight, even frail. A black hat shaded its eye-sockets; its visage, the cast and color of a horse's skull, was expressionless; under the lower edge a complicated set of rasping and chewing parts surrounded a near-invisible mouth. The articulation of the creature's legs worked in reverse to that of the human: it moved forward with the motion of a man walking backwards. The narrow feet were bare and mottled, dark red and black; three arched toes tapped the ground as a nervous man might tap his fingers.

The Pnumekin tunnel monitor spoke softly into the air. "An abnormal situation, when an item of delivery is no more than an empty sack. The passage and the shaft have been scrutinized; the item either was not delivered, or it made evasion by using a secret adit of Quality Seven or higher."

Silence. From the Pnume, in a husky muffled murmur, came words. "Verification of delivery cannot be made. The possibility of a classified adit exists, above Quality Ten, and beyond the scope of my secrets.* We may properly solicit information from the Section Warden."

The tunnel monitor spoke in a voice of tentative inquiry. "The delivery, then, is an item of interest?"

The Pnume's toes drummed the floor with the delicacy of a pianist's fingers. "It is for Foreverness: a creature from contemporary Man-planet. Decision was made to take it."

Reith, cramped in the locker, wondered why the decision had been delayed so long. He eased his position, gritting his teeth against the possibility of a sound. When once again he put his eye to the crack the Pnume had departed. The monitor and the passage-tender stood quietly, taking no notice of each other.

Time passed, how long Reith could not judge. His muscles throbbed and ached, and now he feared to shift his position. He took a long slow breath and composed himself to patience.

At odd intervals the Pnumekin spoke in murmurs, looking aside all the while as if they addressed the air. Reith distinguished a phrase or two: "... The condition of Man-planet; there is no knowing ..." "... Barbarians, surface dwellers, mad as Gzhindra ..." "... Valuable item, invisible ..."

The Pnume reappeared, followed by another: a creature tall and gaunt, stepping with the soft tread of a fox. It carried a rectangular case, which it placed with delicate precision upon a bench three feet in front of Reith; then it seemed to lose itself in reverie. A moment passed. The passage-tender of lowest status spoke first. "When a delivery is signaled by the gong, the bag is usually heavy. An empty bag is cause for perplexity. Delivery evidently was not made, or the item gained access to a secret adit, over Ten in Quality."

The Warden turned aside and, spreading wide its black cloak, touched the locks of the leather case. The two Pnumekin and the first Pnume interested themselves in the crystals of the wall.

Opening the case, the Warden brought forth a portfolio bound in limp blue leather. The Warden spread it apart with reverent care, turned pages, studied a tangle of colored lines. The Warden closed the portfolio, replaced it in the case. After a moment of musing, he spoke in a voice so breathy and soft that Reith had difficulty understanding him. "An ancient adit of Quality Fourteen exists. It courses nine hundred yards northward, descends, and enters the jha Nu."

The Pnumekin were silent. The first Pnume spoke. "If the item came into the jha Nu, he might traverse the balcony, descend by Oma-Five into the Upper Great Lateral. He could then turn aside into Blue Rise, or even Zhu Overlook, and so reach the ghaun."

The Warden spoke. "All this only if the item has knowledge of the secrets. If we assume his use of a Quality Fourteen adit, then we can assume the rest. The manner by which our secrets have been disseminated-if this is the case-is not clear."

"Perplexing," murmured the passage-tender.

The monitor said, "If a ghiant knows Quality Fourteen secrets, how can these be safe from the Dirdir?"

The toes of both Pnume arched and tapped the stone floor.

"The circumstances are not yet clear," remarked the Warden. "A study of the adit will provide exact information."

The low-status passage-tenders were first to leave the room. The monitor, apparently lost in reflection, sidled after them, leaving the two Pnume standing still and rigid as a pair of insects. The first Pnume went off, padding on soft, forward-kicking strides. The Warden remained. Reith wondered if he should not burst forth and attempt to overpower the Warden. He restrained himself. If the Pnume shared the fantastic strength of the Phung, Reith would be at a terrible disadvantage. Another consideration: would the Pnume become pliant with pressure? Reith could not know. He suspected not.

The Warden took up the leather case and turned a deliberate stare to all quarters of the chamber. It appeared to listen. Moving with uncharacteristic abruptness, it carried the case to an expanse of blank wall. Reith watched in fascination. The Warden slid forward its foot, delicately touched three knobs of rock with its toes. A section of wall fell back, revealing a cavity into which the Warden tucked the case. The rock slid back; the wall was solid. The Warden went off after the others.
