A scientist is hired by an ultra-wealthy woman to resurrect/clone her dead husband, as an extension of research he was already doing. "Ultra-wealthy" doesn't even begin to describe it. It is explained that the truly rich are wealthy enough to buy medium-sized countries, and are never in the spotlight because they can always buy off the spotlight and direct it elsewhere. In other words, they're far wealthier than Bill Gates, Warren Buffet, etc.
His patron sets the scientist up on a remote idyllic island to continue his research. IIRC he makes the necessary breakthrough, but too late. As payment he's given an "unlimited" credit card, which he destroys.
He finds out that the island, fishing village, etc. were set up just for him, and are being torn down again. The people on the island were all actors. He belatedly realizes that he might have been able to provide an alternative means of making the woman happy.
