We used Erenegi (V) style encryption. Use your key from last week.

We believe our attempts at finding the defector are starting to
bear fruit. They appear to be working at a math camp at the
University of Utah. We have embedded you at the same camp. Please
remember to use all appropriate expense forms. Also remember that
our health insurance program is changing to Evil Health Inc. Open
enrollment begins next week. Because you missed the mandatory
training seminar on using their website, you will need to schedule
an individual training once you return. Please schedule this at
your convenience between the hours of five and six thirty am on
July fourth. As per standard policy, your next clue is located
behind a garbage can nearby. Remember, if you are captured, we will
make fun of you online and of course disavow you as well. You
should not expect to be rescued.
