My Uncle's Trunk

A stolen inheritance. A dead uncle's secrets. A conspiracy stretching from your front door to the Carpathian Mountains.

When the trunk left to you by your favorite uncle is stolen only days after you receive it, a seemingly simple theft unravels into something far darker. Bureau 13. A mysterious Mr. Blakk. A diary full of secrets your uncle died to protect.
