With the cylinder’s playback complete, the Electric Priestess reveals that, in fact, she is Zeffir’s sister. She was the original head scientist for Zeffir Zeppelins, and lost her leg many years ago in a zeppelin accident which she blames on Zeffir’s cost-cutting. She suspected all along that Zeffir was behind Sam’s parents’ disap- pearance, but felt she must have proof before she could reveal her suspicions to Sam. In fact, she explains, she has been a friend of Sam’s parents for some time, and when they started to fear that they would be caught by Max Zeffir, they broke up the evidence, in the form of the wax cylinder, and scattered the pieces, putting one in their apartment, one in their office in Benthos, and mailing the remaining pieces to Ike, Dulo, and the Electric Priestess herself. The Priestess now concludes with certainty that it has been Zeffir sending robot minions to try to stop Sam from discovering the truth about his parents.
