Let's Settle the Beef With Wo Fat Already ***
10 May 2011 | by (United States) – See all my reviews

It seems that our gang is finally closing in on the terrible Wo Fat. We're almost forgetting the beef we've had with this tyrant.

Danny is exposed to chemicals and if it weren't for the CIA agent on leave, he would have left us. Trouble with that agent is that she is almost churlish in nature as her voice becomes most irritating sometimes. I felt that she reminded me of Betty Boop.

In trying to locate the enemy Mr. Fat and determine why that poison was in the house, we get into a tangled web of deceit, love affairs and everything else as we determine who was the mastermind of putting that poison in the house. As always, the culprit is a surprise.
