<h2>THE THRILLING NEW KAY SCARPETTA MYSTERY FROM THE WORLDWIDE BESTSELLER</h2>

'Iconic. Bold. Brilliant. Identity Unknown is hauntingly original, impossibly clever and devilishly daring. Scalpel-sharp storytelling, trademark twists and characters that feel like family, this series is one of the all-time greats' CHRIS WHITAKER, author of Sunday Times bestseller All the Colours of the Dark

Summoned to an unnerving, abandoned theme park to retrieve a body, Dr Kay Scarpetta is devastated to learn that the victim is a man she once loved. While teaching in Rome during the early days of her career, Scarpetta had a love affair with acclaimed astrophysicist Sal Giordano that led to a lifelong friendship.

The murder scene is bizarre, with a crop circle of petals around the body, and Giordano's skin is strangely red. Scarpetta's niece Lucy believes he was dropped from an unidentified flying craft. Scarpetta knows an autopsy can reveal the dead's secrets, but she is shocked to find her friend seems to have deliberately left her a clue.

As the investigators are torn between suspicions of otherworldly forces, and of Giordano himself, Scarpetta detects an explanation closer to home that, in her mind, is far more evil . . .
