I feel compelled to report that at the moment of death, my entire life did not pass before my eyes in a flash . . . What I experienced was a little voice piping up in an outraged tone: “Oh come on.You’re not serious.

The trouble started on the very first day of the investigation.Either Kinsey’s predecessor was incompetent – or someone had been getting away with murder. And next time it might turn out to be hers . . .
