 To cut a long story short, the tramp is none other than Pope Alexander VI, the last of the Borgias, and the beans grow into hideous homunculi, whose only purpose is to serve their dark master, the Antipope.Pope Alexander takes up residence in the local Seaman's Mission, and eventually there is a final showdown between the forces of good and evil, with Alexander and his bean-men on one side, and the massed might of Brentford on the other, including Pooley and Omally, Professor Slocombe, Father Moity, and Archroy, now a master of Dim Mak, a deadly martial art.Before the denouement, though, there are numerous sub-plots such as Channel-wading, a cowboy night at the Flying Swan, a trip underground with Soap Distant, and meetings with several other interesting characters, like builders Hairy Dave and Jungle John, and the elusive Other Sam.
