A Season for the Dead by David Hewson (Nic Costa Mysteries #1) (Paperback)

“Whilst Sara Farnese pores over ancient texts in the silent Vatican reading room, a brutal murder is taking place in a nearby church. Then suddenly a crazed man arrives in the Vatican carrying a bloodied bag. He walks up to Sara’s desk. He has something he would like her to see.
Soon Sara is inextricably linked to a series of horrific and cunning murders, each one in some way symbolizing the death of a Christian martyr.
Into this climate enter Detectives Costa and Rossi, enlisted to track down the killer, and to protect Sara from the horrors she is doomed to confront…”
