Overpayment scam alert / Fake check

I got a check!!!

God knows, who from, for the amount I've never earned, from the country I can't find on the map. The good and honest payer on the other end is sleeping tight, knowing that I am an honest person too, which became obvious immediately after I provided him with all my livelihood data on a first email demand. He knows that I shall not eat or sleep before wiring some poor soul 4500 miles away, whose chunk was sent to me by mistake, h/h her honest share; his accountant sleeps even tighter knowing that a) he does not have to mess with stopping the payment, b) the money will be bouncing all over the world after having been handled by a stranger from a foreign country, and, after all, he knows how to enter all this dancing under the stars properly into the books for tax authorities...

But I am a smart and cautions person, I still have my doubts, so I'd better do my due diligence - deposit that pretty check and see what happens...

Mamma mia ...
