Castle Wulfenbach/Mad

Fate
Given that a good number of the statements directly referring to the Castle, such as "it never lands", "have Captain Patel scuttle the castle", and "the castle is in flames, and I've lost my hat" have an eschatological character (especially compared to aphorisms common in American English such as "what goes up must come down" and "the bigger they are, the harder they fall") one wonders if the end of Castle Wulfenbach will eventually form a climax to a future volume, act, or indeed, the whole story. (We won't discuss Castle Heterodyne's comments in relation to that last clause, okay?)
