The fourth riveting novel featuring the incomparable Dr. Samantha Owens, by critically acclaimed New York Times bestselling author J.T. Ellison Waking to sirens in the night is hardly unusual for Sam Owens. No longer a medical examiner, she doesn't lose sleep over them, but a routine police investigation in her neighborhood has her curious. When her homicide detective friend, Darren Fletcher, invites her to look over the evidence, she immediately realizes the crime scene has been staged. What would seem to be a clear case of murder/suicide is anything but. The discovery of toxic substances in hidden vials indicates that something much more sinister is at play... As Fletch and Sam try to understand what and who they are dealing with, they are summoned to a meeting at the State Department. High-level officials are interested in what they know and, as the threat of bioterrorism is exposed, seem to be keeping secrets of their own. Unsure who to trust, Sam and Fletch find themselves up against very powerful people at every stage in the investigation. It's Sam's most complex case yet, and the terrifying reality is beyond anything she could have imagined.
