Blood Sisters

Katie Maguire hunts a serial killer targeting nuns in the gruesome new thriller from Graham Masterton.

In a nursing home on the outskirts of Cork, an elderly nun lies dead. She has been suffocated. It looks like a mercy-killing - until another sister from the same convent is found viciously murdered, floating in the Glashaboy river.

The nuns were good women, doing God's work. Why would anyone want to kill them? But then a child's skull is unearthed in the garden of the nuns' convent, and DS Katie Maguire discovers a fifty year old secret that just might lead her to the killer... if the killer doesn't find her first.
