. About once a year the police had "cleaned out" the ruins by dropping a few retch-gas bombs down the more conspicuous holes; it simply meant having to sleep somewhere else for a couple of nights. But this was a raid in force. They had intended to arrest Pop and they had been searching for something.
The Sargon's police operated on a concept older than justice; they assumed that a man was guilty, they questioned him by increasingly strong methods until he talked . . . methods so notorious that an arrested person was usually anxious to tell all before questioning started. But Thorby was certain that the police would get nothing out of Pop which the old man did not wish to admit.
Therefore the questioning would go on a long time.
They were probably working on Pop this very minute. Thorby's stomach turned over.
He had to get Pop away from them.
How? How does a moth attack the Presidium? Thorby's chances were not much better. Baslim might be in a back room of the district police barracks, the logical place for a petty prisoner. But Thorby had an unreasoned conviction that Pop was not a petty prisoner . . . in which case he might be anywhere, even in the bowels of the Presidium.
Thorby could go to the district police office and ask where his patron had been taken -- but such was the respect in which the Sargon's police were held that this solution did not occur to him; had he presented himself as next of kin of a prisoner undergoing interrogation Thorby would have found himself in another closed room being interviewed by the same forceful means as a check on the answers (or lack of them) which were being wrung out of Baslim
