About this audiobook

Bloomsbury presents Blood Sisters by Graham Masterton, read by Lucianne McEvoy.

Why would nuns need protection from a killer?

In a nursing home on the outskirts of Cork, an elderly nun has been suffocated in her sleep. It looks like a mercy-killing – until another sister from the same convent is found 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 they don’t find her first.

'One of this country's most exciting crime novelists.' Daily Mail

Perfect for fans of Peter James, CJ Tudor and Chris Carter, Blood Sisters is part of the darkly original million-copy-bestselling DS Katie Maguire thriller series, which can be read in any order.
