A small crisis has just come up at the lab that we 
think your group would be able to help with.

One of our tech writers, Antoine Molson, has suddenly 
disappeared.  We have reason to suspect that he might
have been a mole from some external group, possibly
connected to some government agency that is trying to
keep tabs on our groundbreaking work.

Mostly we base this suspicion on 
the fact that we couldn't ever understand the documents
that he revised for us in preparation for publication to
scientific journals (he just assured us that that's what
professional scientific writing looks like).

We're sending you both a sample of some recent writing 
he did for us, and some awfully suspicious stuff he
left in the office shredder.  If he's trying to 
send some secret messages to his superiors we
bet it's in there somehow.  See if you can find any 
secret messages and, ideally, deduce who he's 
working for.
