Private Investigator, Frank Tidsdale, was visited by Attorney General Patrick Greene who wanted Frank to investigate corruption in the Criminal Court System. AG Greene suspected there was at least one judge who was taking money to control the outcome of trials of mob members. Since AG Greene also suspected a mole in his office, he was looking to Frank to be an independent investigator, and gave him the name of one of the judges he suspected was dirty. Frank began by finding out as much as he could about the judge. He was just getting into the investigation when the judge was assassinated. The death of the judge did not stop his investigation, but changed the direction of his investigation into whom had the judge murdered, and why. He eventually discovered how deep within the Criminal System the corruption went, and who was involved, but not without personal harm to himself. Death by Assassination is the second Frank Tidsdale Mystery.
