Unnatural Acts

This is an okay book written by Stuart Woods. When a hedge fund billionaire hires Stone Barrington to talk some sense into his wayward son, it seems like an easy enough job. But as Stone and his erstwhile protégé, Herbie Fisher, probe deeper into the case, he realizes that even he may have underestimated just how far some people will go to cover up their crimes and plan new ones.

This is the 23rd novel in the series.
