Now at the observatory, Joseph Snorquel looks for professor Wolff.  He ponders on  the nature of silence a strange story told by  Colonel Nancarrow of a Cult of Silence, but his reverie is disturbed by the sounds of the Two Gentlemen.  Incensed, he sets off to investigate and finds the place guarded by local mudmen. A sonic gun battle ensues in which Snorquel employs an infrasonic weapon called the Chunderbuss, delivering a nasty dose of the Brown Note. All soiled.
