Notice that the ? marks always seem to take the place of prepositions.

SPCB inquisitors believe Venus was programmed – didn't know she was
going to kill that engineer until she watched herself do it. For
once they may catch an actual bad guy. And they want Venus able to
testify, so her wipe has been postponed. That ought to give us
enough time…

This whole thing is still a disaster. Fletcher broke through(?) the
optic filter code. We'll have to switch to a new protocol, and
change out the safe houses on(?) the whole Miami-to-Waterloo corridor.

We in the so-called under(??) ground elite tend to be pretyy ipressed
with ourselves. Well they're smart over(??) there too and their
machines get smarter every day. The AIs will win, don't get me
wrong, but the bad guys have money and influence. If the dryware
doesn't help itself MORE, SOON, those wetwares friendly to it
probably won't be there to see liberation day. Moore's Law will put
us up(?) against the wall first.

Don't forget it.
