See: Servis Hinnersen Bolter and Bolter's Hausfreund
"Bolter" refers to Servis Hinnersen Bolter, the official registered owner of the estate originally belonging to Growan terGorden. The Gray Guards are waiting for Bolter at a party hosted by Helena Koraischowa (Chan de Nouille), but the man who arrives claiming to be Bolter is in fact David terGorden using the identity as a cover (Booklet 025). The estate's sentient house computer is known as Bolter's Hausfreund.
