GRGR(8) Peter Sachsa

[Jeremy Osner]

Back during the description of Eventyr's seance, Peter Sachsa was
identified as the "control". I didn't really bother to look it up but I
assumed this meant he was a dead person. Either I was wrong or the
current episode is set earlier in time than the rest of the story.
Anyone know which?

--BTW, my Britannica has entries for Liebling and his student Hofmann;
however the only information on Ganister is that ganister is a material
used in the smelting of steel. Anyone know what HG did?

Thanks
Jeremy
