A class act is a class act. It goes horribly wrong, usually involving a dead body that Bernie is liable to be blamed for. He puts more work into solving the crime than into the original burglary. He evades the police and solves the crime.
Burglary goes wrong.
Bernie solves it. But this is like saying the Jeeves books are about a man and his butler. To sustain a fairly limited joke over two decades is no mean feat, and at least half the pleasure is in seeing if we can spot Block sandbagging us again. Nope, missed it. They're not called by those names you understand, but by ones even less believable.
