The start of a dark, gripping crime thriller series from UK Top 50 bestselling author John Nicholl

Be careful who you trust.

The Mailer family are oblivious to the terrible danger that enters their lives when seven-year-old Anthony is referred to the child guidance service by the family GP following the breakdown of his parents' marriage.

Fifty-eight year old Dr. David Galbraith, a sadistic, predatory paedophile employed as a consultant child psychiatrist, has already murdered one child in the soundproofed cellar below the South Wales Georgian townhouse he shares with his wife and two young daughters.

Anthony becomes Galbraith's latest obsession and he will stop at nothing to make his grotesque fantasies reality.
