Dearest Perin,
After telling you earlier about our disastrous attempt to explore some caves outside the city, I finally recalled the name of the fellow I spoke to you about.
His name was Alpin, I think. Of course, there is no proof he took all those things while we lay hurt or dying, he was the only person (or body) missing when we were able to take stock afterwards. Too much was missing for it to be a coincedence.
If you meet him or deal with him, watch him. He may be innocent, but he also may not.
Yours in trust, Eowung.
