Tagline: He’s back!

Actuary’s brother is undead, and has learned nothing from the near death experience. Bad, very bad, for many reasons which Actuary enumerates…at length. Brother is a one-man wrecking crew, filled with good intentions that generate catastrophes, which he duly blames on the nearest innocent bystander. He would seem well qualified for senior management, and he is just that in his own freely given opinion.
Actuary is also so in love, he cannot calculate the cost-benefits of anything, starting with being in love. He speaks without thinking! He makes schoolboy blunders in arithmetic! He takes the bus when he meant to go by train. He turns the wrong way when he exits the bus and gets lost. He is not himself. But then who is he? Indeed, where is he? On the wrong bus.
And, ‘What about the moose?’ A moose in need is a friend indeed. Right, Rocky!
***
Does not compute: the police show no interest in Brother’s return from the dead. I also found Johanna’s capitulation to Brother did not jibe with her no nonsense persona from the Rabbit Factor.
