The Jefferson Legacy — Nick Thacker

Meriwether Lewis was murdered because he knew a secret....A deadly secret. From the author that brought you the best-selling Harvey Bennett Thrillers series, The Jefferson Legacy is the newest installment in the series, and the first featuring the fully formed "Civilian Special Operations" team. Harvey Bennett is back. Ben and his new team are hard at work putting the finishing touches on their "Civilian Special Operations" headquarters, when they get a call: there's been a murder, and a theft of a seemingly insignificant artifact. The team heads to Philadelphia to meet up with the modern-day American Philosophical Society, to talk about the robbery and see if they can offer help....soon, bullets begin to fly. Apparently the APS has been keeping secrets that point all the way back to the nation's Founding Fathers.
