Plot Conundrum Solved

I started the new novel, Killer Ratings, and I got to just over 7,000 words when I realized that I was writing myself into a corner. You see the story starts at a cooking competition called Sliced where four chefs compete in three elimination rounds consisting of appetizer, entree and desert. In each round a secret ingredient must be used and one competitor is eliminated. After the second round one of the judges dies from what looks like a heart attack. Later it is discovered that he is poisoned by cyanide.
Now the problem I had was exactly how the one judge was the only one affected and not the other two, or Ian Wallace who is the host of the show. Well, I solved it with an interesting plot twist and now have the final chapter fleshed out. I won't say what that twist is, but it works in an old fashioned detective sort of way. Now I can get working on this.
On another note copies of the two Port City Mystery books will be auctioned off at the Cape Fear Literary Council's Casablanca event and the winner of the bidding gets a walk on role in the new book.
