When the mayor of New York City's grandson and the grandson's wife are murdered execution-style in their Tribeca apartment, NYPD Detective Louis Martelli and his partner,Detective Sean O'Keeffe, are left completely in the dark. Months go by without any actionable leads until a meeting with the wife's doctor and the bizarre torching of Stephanie Martelli's car turn the investigation upside down and land Martelli and O'Keeffe in the hotseat. When an old friend of Pietro Martelli's, Louis's deceased father and a former street cop who had been gunned down in the line of duty, sends Martelli a note asking for a meeting, things take an even stranger turn. The evidence in this mob-driven case of political corruption, bribery, and murder pits the two detectives against their boss, Captain Hanlon, Police Commissioner Eugene Fields, and His Honor the Mayor. Can Martelli and O'Keeffe survive this kind of pressure and keep their jobs, muchless solve the case? You'll have to read Eighth Circle to learn the answers. Note: Books in this series may be read in any order.
