Douglas Monaghan welcomes back one of his former students, Peter Locke, now a professor who has made quite a name for himself in North America. Craig Stephenson studies the case of John Wade, a self-styled mentalist who has a successful stage show. Although he amazes his audiences, he is clearly using well-worn techniques to correctly guess information of audience members. There are a few anomalies however. Justine McManus meanwhile travels to a psychiatric hospital to investigate the case of a woman who claims she is the survivor of a shipwreck that occurred in 1904 - but only washed ashore in 2004.

John Wade is convinced that he can cure young Chloe Williams of her brain tumor. Craig Stephenson is quite skeptical but newly arrived Peter Locke isn't and is quite keen to study the case. As they learn more about John's background and family history, they realize there may be a more than reasonable explanation for his behavior, though not all can be explained away. Justine McManus goes to Patience Green's home village and finds that it is much as she described it. Her knowledge of the locality and of the people who lived there is astounding but Patience does make one slip that leads Justine to believe there is an explanation for both her condition and her degree of knowledge about the community.
