The Altar Girls by Patricia Gibney

When Detective Lottie Parker receives news that a child's body has been found in the cathedral grounds, she's terrified it will be eight-year-old Willow, reported missing that morning.

But when she arrives at the cathedral, she gets a shock. The body is a young girl, wrapped in a white shroud. However, this girl isn't Willow but another eight-year-old, Naomi.

Desperate to find a connection between the two girls and to find Willow, Lottie discovers that both girls were altar servers at the cathedral. The priest has an alibi, but Lottie suspects the old lady who discovered Naomi's body hides something.

A day later, Willow's body is found wrapped in a white robe. And when a little boy from the choir goes missing too, Lottie realises she must spread her net wider. Can she stop this killer?

A completely compelling page-turner from bestselling author Patricia Gibney. If you like Rachel Caine, Kendra Elliott and Robert Dugoni, The Altar Girls will have you hooked.
