Calvin Sandfire was involved in the abduction of Edward Longknife and stated that Kris Longknife was the actual target. Sandfire abducted Tom Lien to lure Kris Longknife into a trap then deliver her naked in chains to Henry Smythe-Peterwald XII. When things when badly for Sandfire on Turantic, he attempted to destroy Kris's vessel but she destroyed his instead.

Sometime before the events in Defiant Kris told her brother Honovi about Sandfire's plans for her.
