Not Isabel’s flesh but Lorelei’s, the same Lorelei who wows the corrupt police chief, Sarpina, with her virtuoso vocal performances.

His animated arms knock down the man standing behind him repeatedly until all three servants simultaneously quit. They storm off into the adjoining kitchen where a slavery maid (Blanche White) is on the floor scrubbing the floor. The men all trip over her, moan briefly and then leave.
