Hollow Sky - M. Sean Coleman - Bog

A SUSPENSEFUL, ATMOSPHERIC THRILLER.
Jane Hewitt had a miraculous healing-after one meeting with a faith healer, Jane rose from her wheelchair and walked, seemingly cured of her terminal cancer and believing that her lifetime of devoted faith had been rewarded.
Jane died the next day, devastated that her God had deserted her. Her husband, Ian, blames her hastened death on the faith healer she visited, and turns to Dr Alex Ripley-the so-called Miracle Detective-for help.
Fascinated by the case, Ripley finds herself on Holy Island, off the coast of North Wales, caught up in an investigation that will prove more sinister and dangerous than even she could have imagined.
Ian is not the first person to complain about this particular faith healer, but he's the only one still alive. For now.
