I loved the setting in Ireland and the very real characters, especially Sheehan with his faults and virtues. For lovers of Dan Brown, the plot twists and religious tones are similar in the Doom Murders. Also, Sheehan's intuition and grit is similar to Professor Robert Langdon in the Da Vinci Code. It's a race to end and readers are satisfied to discover the killer. I totally recommend the book and look forward to the next story in the series.
