Jack Solo is a poker playing, wisecracking Chief Inspector with the United States Marshals Service. He is contacted by Megan McGrady in Washington DC, where she is a teaching assistant in the art history department of George Washington University. She heard of a plot to steal four volumes of the Book of Kells from Trinity College in Ireland. As Jack begins his inquiries, Megan is pushed in front of a blue-line train in Georgetown. Jack is recruited by Interpol to investigate her untimely death, leading him to Dr. Alexander Mikhailov-Megan's boss. Alexander is a lot more involved than he'd like to let on. In fact, a Russian crime syndicate is blackmailing him to steal the Book of Kells, as Megan warned. Jack is on the hunt to avenge Megan and save a priceless historical artifact. His travels take him to Ireland and eventually Costa Rica. He is able to recover the volume containing the Gospel of John, but the Gospel of Luke is still missing.
