A serial killer is on the loose in the Vatican...

In the days following the death of Pope John Paul II, 115 cardinals are called to the Vatican in order to take part in the conclave and elect the new Pope. With Rome under siege to foreign press and thousands of mourners, the last thing it needs is a serial killer on the loose...

Paola Dicanti is a profiler who works with the Italian police. She has been put in charge of profiling serial killers in a department of one - i.e. herself - but so far all her experience of serial killers is theoretical. This is until she is called to the church of Santa Maria in the Vatican state. A cardinal has been found murdered, his eyes destroyed, his hands cut off. It seems that this is not the first victim - another cardinal was found in similar circumstances but the authorities didn't want a scandal.

Recovering from a bitter affair with her boss, Paola begins to build her profile using information from the scene of the crime, from the autopsy, and from forensic evidence. She is helped in this by Anthony Fowler, a priest from the States. But it turns out that Fowler is no ordinary priest - he clearly has links to the CIA, and knows a lot about the serial killer than Dicanti could ever have guessed...
