Either Gerard did it or he didn't...if he didn't murder Alison he has to be the luckiest bloke on that day in the whole world... here you are , say,, a demanding and relentless mistress plus a few extra bonks thrown in here and there..a mistress who gives ultimatums, no less.. and one on that day , too!
Your wife has found out that you have recommenced an affair you said you stopped. You have to attend counselling sessions..this wife is also at your office now, where everyone knows the trouble you are in.
You owe money... big gobs of it, to your father , to banks, to partners, to god knows who, ( but we WILL know to whom shortly )business is failing rapidly, yet just as rapidly the deadline for payments are looming. No one will lend you any more. All your talk and blather has not moved these horrors one centimeter..
The ONLY asset that is even remotely possible is insurance on your wife, and her superannuation payout... but this is remote and untouchable.. UNLESS...
Then out of the blue, one morning... just an ordinary morning, up and showered and shaved, get kids lunches, you find that some kind stranger has solved ALL your problems for you by abducting and killing your wife!!.... how amazing is that>???
