An entertaining read although not a brilliant one. I may have too high hopes for Wodehouse in general.
Part of the problem may have lain in the fact that throughout the book, Bertie insists on attempting to puzzle out solutions to the various problems himself rather than rely on Jeeves.
Mild spoilers (probably fine, but I am giving away the newts a bit):

Meanwhile, Bertie keeps coming up with schemes on his own rather than rely on Jeeves because he thinks Jeeves's are too elaborate. To be fair, Jeeves's proposals are a bit elaborate, especially the last one.
