The New York Times bestselling Kay Scarpetta series is now an original series on Amazon Prime! To stop a diabolical series of mysterious murders, Dr. Kay Scarpetta must hunt for a killer who leaves no trace, in the newest thriller from #1 New York Times bestselling author Patricia Cornwell. A billionaire couple, founders of an elite security firm, are found dead in their mansion, apparently stung by yellow jackets. The victims were both highly allergic and there are no signs of foul play, but Virginia chief medical examiner Kay Scarpetta suspects the case may not be as straightforward as it seems. When she uncovers a link between the couple and another body in her morgue, her worst suspicions are confirmed: these deaths were anything but accidental. Only a highly sophisticated criminal could pull off these murders completely undetected. And only Scarpetta can stop the monster before he strikes again.
