Where five senses meet, a sixth is born...In a quiet, residential neighbourhood of Portland, Oregon, an unknown young woman uncovers a shocking crime scene by inexplicably sensing the evil within its walls. To the police, she herself is a mystery. She appears on no government records, has no past and can't even tell the police her own name. Christened Jane Doe and suffering terrifying hallucinations, she is assigned to Nathan Fox, a forensic psychiatrist struggling with his own demons after witnessing his parents' murder as a child. Together they must piece together the jigsaw that is Jane's identity. Then a sequence of brutal killings terrorise the city and Fox learns Jane is the only cryptic link between the unrelated victims. To solve the murders, discover who she is and diagnose her condition, Fox must discard his black and white preconceptions, look beyond the spectrum of normal human experience and confront the dark truth of her past ...and his own.
