where can one find von speyr's works in german?

In the USA, finding Adrienne von Speyr's works in German can be difficult.  You can purchase most of them from the Johannes Verlag.  If you are looking for some of the privately published works (i.e. a few volumes of Die Nachlasswerke), you will have to try interlibrary loan through your own library.  The Alcuin Library at St. John's University has the most complete collection of Adrienne von Speyr in German, except for the second volume of Kreuz und Hoelle.  I would very much like to find a copy of this second volume.
