A Forensic Pathology Thriller · The Giselle Norwood Prequel
When the courtroom becomes a battlefield, a young forensic pathologist is determined to shine a light on the truth. Dr. Giselle Norwood's quiet life is upended when a defence lawyer drags her into a murder trial. What looks like an open-and-shut poisoning case unravels into layers of deception — and a race to save an innocent man before it's too late.
"The perfect appetizer for the Giselle Norwood series. Great mix of courtroom drama and medical thriller. Wonderful twist at the end."
★★★★★ — Goodreads Verified ReaderThe Flagship Series
D.C. Medical Examiner Dr. Giselle Norwood is an expert in the language of the dead. But when a serial killer calls her directly — and offers to help catch a copycat — she realises this case is bigger than Washington, bigger than the US.
Reader Reviews
"Outstanding, a great page-turning thriller. Well-written, entertaining, with well-developed, memorable characters. Maybe her best book I've read. Strongly reminiscent of the writing of David Baldacci."
"The characters and plot gripped me from the beginning and I couldn't put it down. Definitely one of the very best books I've read in the last couple of years."
"Time of Death lifts Audrey Walker into the very top tier of contemporary crime writers. The plot is intense and totally engaging. The characters are drawn with razor-sharp precision."
