“Thank you again for this.”

Terminator began to glide past the platform that held the Tintoretto tram station. They walked through the lock directly into a waiting tram, along with about a dozen other people.

The tram, when it departed, moved much faster than Terminator did, zipping off west on ordinary tram tracks and soon reaching a couple hundred kilometers an hour.

Swan identified a long low hill on the horizon as the outer wall of Hesiod Crater. Wahram consulted his wristpad: “We slide between Hesiod and Sibelius,” he announced with a little smile. His pop eyes had brown irises, flecked with radial streaks of black and pumpkin. His wristpad meant he probably did not have a qube stuck in his head, and if he did, it would not be a bitch trying to ruin his day. Pauline was murmuring stuff in her ear, and when Wahram got up to look out the other side of the tram, Swan muttered, “Don’t bother me, Pauline. Don’t interrupt me, don’t distract me.”

“Exergasia is one of the weakest of the rhetorical devices,” Pauline opined.

“Be quiet!”

After another hour they had a good lead on Terminator, and the tram glided up to the outer wall of Tintoretto Crater, where the tracks led into a tunnel in the rugged wall of old ejecta. As they exited the tram, it announced they had two hours before it would return to the city. Through the vestibule of the museum, then to a long arcing gallery. The inner curve of the chamber was a single recessed window wall, giving them an excellent view of the crater’s interior. It was a small but steep-walled crater, a handsome circular space under the stars.

But her Saturnian did not appear to be interested in Mercury. He walked facing the outer wall of the gallery, moving slowly from painting to painting. He planted himself in front of them each in turn, stood staring impassively.

The canvases ranged in size from miniatures to gigantic wall-fillers.
