Following the work of detectives through a series of murders, is an arduous journey. 

This story involves a simple murder, finding how ponzi scheme criminals operate and what they do with ill gotten gains.   Avoiding taxes and moving money from country to country without detection is only the tip of the iceberg. Also, finding an assassin, who is so stealth, that no trace of his murders can be found. 

Finally the faith and trust people have in one another is shattered.
