His security looked at him as if he and his entire species had run mad in the streets.

The world is getting more and more complex and we get more background information on the characters as well as their family relationships. Politics are heating up, too. I'm reading this entire series as one long, very enjoyable novel. As always, Banichi has got THE best lines.

“We have to advise the Mospheirans,” Bren said. “For diplomatic reasons, for courtesy if nothing more. If they think we’ve double-crossed them, they’ll deal with the other side. They’ll conclude they can’t trust us. They have to have the same chance to get out of here. They have to know we’re on their side.”
“One can hardly speak securely on the intercom with them,” Banichi said.
“One can’t” he agreed, trying to think what to do.
“It’s not that far,” Banichi said. “I can walk there, too, and talk to Ben.”
“You’ve had a drink. You’re not on duty. No!”
“I might have another. If I’m walking the halls, I am doubtless an inebriate having strayed from duty, and will say I require Kaplan to guide me home. Humans understand inebriation. I recall your machimi. They consider it quite amusing.”
“Not when you’re damned guilty and in the wrong corridor. We’re not supposed to be able to open these doors.”
“One would certainly have to admit to that.”
“And there’s the problem of making the Mospheirans believe you when you get there.”
“Give me a token for them. Is this not machimi?”
“One will be prostrate with nerves the whole damned time,” Bren muttered, seeing less and less chance of dealing with a situation run amok. “One has not the least idea what Kroger may do. The woman distrusts me very easily. We simply can’t—”
“A banner is traditional.”
“Not among humans. Rings. Letters.” It was preposterous. “It’s a damned comedy, is what it is.” Banichi wasn’t one to propose lunacy. He had the feeling of being maneuvered, backed toward an ultimatum.
“We can hardly do this by intercom,” Banichi said, silken-smooth and one drink down.
“I can simply invite them to dinner and tell them face-to-face. No more wandering about the halls. By no means.”
Banichi sighed. “One did look forward to it.”
