Sparkling Cyanide.

I am making my way chronologically through Christie's mystery novels and I am unsure how I feel about this one. It was not the most exciting, nor the most surprising. On the other hand, it wasn't the most obvious either. But overall, I enjoyed reading it. All of her books are worth reading.

I know they like to categorize the books by detective, but this hardly counts as a Colonel Race novel. That is, he does play a significant part in uncovering the mystery but doesn't, in the end, solve it.
