James Baron, awaiting a Brightside Crossing attempt, is intercepted at the Red Lion by a scarred, weary stranger who turns out to be Peter Claney, the only survivor of a prior attempt to cross Mercury's Brightside at perihelion. Claney insists Baron's expedition cannot succeed and recounts his own journey to explain why. Claney's interest in the Brightside dated back to childhood, following the failed, ill-equipped attempt by Wyatt and Carpenter in 2082 and later the solar research of Sanderson at the Twilight Lab. Major Tom Mikuta, a seasoned explorer who had worked with Claney on Venus and led the Vulcan Crater expedition, proposed the Crossing and recruited Claney, insisting on tackling the Brightside at perihelion via the surface rather than the easier aphelion route. They based preparations at Sanderson's Twilight Lab near Mercury's pole, where Jack Stone, a young, devoted protégé of Mikuta, had assembled Bugs (light vehicles) and sledges. A fourth member, Ted McIvers, a reckless, restless climber, joined late after arriving via Venus. Mikuta briefed the team: Claney would drive the lead, stripped-down Bug to scout terrain; Mikuta and McIvers would flank him; Stone would haul the sledges. McIvers pushed unsuccessfully for a solo advance-scouting role, but Mikuta refused, insisting the party stay together. Equipped with fiberglass-and-chrome insulating suits and refrigeration units, they set out on a thirty-day, seventy-miles-per-day schedule toward Center, planning a further two-thousand-mile trek afterward to be met by Sanderson's scout ship. The journey grew brutal under the enormous Sun: constant thirst, sleeplessness, and eye and skin strain. The terrain held molten-lead mires, zinc sloughs, sulfur pools, and unstable crusts. McIvers grew increasingly impatient and reckless, once racing his Bug across an unverified zinc ledge against Claney's judgment, provoking Mikuta's fury. The group also discovered the wrecked half-track Bug and skeletal remains of Wyatt and Carpenter. Meanwhile Stone became visibly terrified, confessing his fear to Claney one night, though he resolved to continue. Falling further behind schedule, the party pushed harder. Crossing another treacherous ledge, Claney halted after sensing danger, but McIvers drove out onto it anyway; the shelf collapsed, plunging his Bug into a crevasse. McIvers survived, badly injured with a failed cooling unit, prompting a rescue attempt: Mikuta and Stone descended by cable while Claney operated the winch. Before they could complete the rescue, the ledge gave way entirely, killing all three men in a massive collapse of rock, zinc, and lead. Claney, left with only the tractor and sledges, endured a seven-day solitary drive back. Concluding his account to Baron, Claney argues the expedition failed not from any single man's error but because the planet and Sun itself are insurmountable — McIvers' recklessness was as necessary as Mikuta's caution, and the failure was inherent to the venture. Baron remains resolved to attempt the Crossing regardless. Pressed on why he came, Claney admits he meant to talk Baron out of it, but when accused of lying, he breaks down and instead asks to be taken along on Baron's expedition.

JAMES BARON was not pleased to hear that he had had a visitor when he reached the Red Lion that evening. He had no stomach for mysteries, vast or trifling, and there were pressing things to think about at this time. Yet the doorman had flagged him as he came in from the street: "A thousand pardons, Mr. Baron. The gentleman-he would leave no name. He said you'd want to see him. He will be back by eight."
