A potential terrorist attack and the Lincoln assassination conspiracy plot? Antique boat enthusiast and sometime intelligence agent Steve Stone lives in isolation in an island tower in New York’s Thousand Islands region until he decides to solve an historical murder mystery dating back to the Lincoln assassination. Enlisting the help of Jill Matson, a beautiful young woman with knowledge of Civil War and local history, their efforts to solve the mystery of who murdered the Hermit of Maple Island are progressing when Steve is abruptly summoned to find a terrorist who caused the death of his friend years ago – and who is hiding in plain sight while planning an attack on America as an “audition” for ISIS. Steve and Jill are drawn into danger as they race to locate the terrorist, who appears ready to launch the attack. Can they succeed in thwarting Steve’s nemesis, even as they appear to have discovered a way to prove the Hermit’s involvement in the Lincoln assassination conspiracy and possibly recover valuable treasure and historical documents?
