The nineteenth book in the Kay Scarpetta series, from No. 1 bestselling author Patricia Cornwell.

'America's most chilling writer of crime fiction' The Times

Kay Scarpetta has arranged to meet an inmate at the high-security Georgia Prison for Women. The prisoner is a convicted sex offender and the mother of a vicious and diabolically brilliant killer.

Against advice, Scarpetta is determined to hear this woman out - she believes she may hold some answers to the murder of her former deputy. But soon she finds connections to a string of grisly killings.

As she learns more, Scarpetta is compelled to conclude that this is only the beginning of a terrifying terrain of conspiracy on an international scale. And she is the only one who can stop it . . .

The next book in the Scarpetta series is The Bone Bed. And the brand-new instalment, Identity Unknown, is available now!
