There were things at Teind House that must be kept concealed from the prying world at all costs . . .

Selina March has lived in the remote Scottish hamlet of Inchcape, with its mysterious Round Tower, for nearly fifty years. Brought up by elderly relatives, long since dead, she now lives alone, shunning the outside world as much as she can. But when she reluctantly accepts a paying guest, Selina’s secluded life will change for ever. Crime writer Joanna Savile has come to Inchcape to research her latest novel by interviewing inmates at Moy, the asylum for the criminally insane situated nearby. Her secret aim is to question former child murderer, Mary Maskelyne, Moy’s most infamous patient.

Joanna’s prying will yield unexpected results. For, although they have never met, Selina March and Mary Maskelyne are connected by a shared family tragedy: a terrible act of unspeakable cruelty that took place in India fifty years before. And there are secrets in Selina’s more recent past, too. Secrets that are about to be uncovered with the most devastating and shocking consequences . . .
