"The solution is of the colossal ingenuity we have been conditioned to expect." (Times Literary Supplement)
"The infallibly original Agatha Christie has come up, once again, with a new and highly ingenious puzzle-construction." (New York Times)

There was supposed to be a fake murder, it becomes real. How much more predictable does it need to get? Throw in also the murder mystery writer. With such cliched premises, it is hard to save the plot after that, no matter what twists there are.
