?'Jane Halifax out of her depth and at her best. I could not put it down.' Rebecca Gibney, television's Jane Halifax

?JANE HALIFAX IS ABOUT TO DISCOVER THE GRITTY UNDERBELLY OF SILICON VALLEY

Within hours of arriving in New York City, Jane is dragged into a case and finds herself up against one of the toughest minds she's ever had to crack: a Silicon Valley billionaire whose ex-business partner has just been murdered.

Sarah Noble is the darling of the tech world - the genius behind an AI defence system that hijacks enemy missiles. But when Sarah's estranged business partner is killed in a mysterious plane crash, suspicion immediately falls on one of the few people who could hack the plane's guidance system and had a motive to do so: Sarah herself.

Against her better judgement, Jane agrees to profile Sarah and is immediately drawn into a world beyond her control, where money is no object, murder a tool of trade and the stakes go straight to the heart of the United States itself.

Jane Halifax will need all her forensic experience to unlock the secrets of one of the world's most formidable minds.
