“The Abomination” by Jonathan Holt (Harper Collins, 448 pgs., $25.99)

Don’t be deceived by the title, “The Abomination.” There’s nothing unreal about Jonathan Holt’s excellent first mystery.

It’s solidly based in present-day Venice, with two women protagonists, Captain Kat Tapo of the Cabinieri and an American Second Lieutenant Holly Boland.

The “Abomination” is the washed-up body of a woman dressed in the robes of a Catholic priest — something that is viewed as desecration by the church.

The third major player is Danieie Barbo, the creator of Carnivia, a worldwide online game based on Venice itself. Barbo, a reclusive genius who inherited a vast fortune but lives in his family’s decaying Palazzo awaiting sentencing on hacking and pornography charges — charges that may not be true.

Tapo is assigned the job of discovering who the Abomination really was and what she was doing in clerical garb. Boland becomes swept into the hunt when it turns out the military and the CIA is involved. Barbo and Carnivia is a touchstone for finding the path to the bigger mysteries. Throw in the 1990’s Bosnian war, human trafficking, sex discrimination, the Catholic Church’s views on women priests, drones, and you have a heady mixture for a first mystery.

While the plot sometimes becomes too tangled for comfort, and the parts of the finale border on disbelief, there is something about “The Abomination” and Carnivia that is fascinating. Even if any of the three major characters don’t return for the next two novels, the set-up is in place for future reading.

“The Abomination” leaves you hungry for more.
