To one of us, seekers of the truth.

We realise that you wanted to be left out of this after what happened last time, but we are in a dire need of your expertise. We recently lost contact with the Professor after receiving his urgent report. We think that some kind of clue can be hidden in the report, but we are not able to find it. We hope that, as you worked with the Professor for some time, you will be able to find it.

Contact us if you are able to find anything.
