In San Francisco for a book signing, Jessica is surprised when her old friend, insurance investigator and former jewel thief Dennis Stanton, drops by to visit. He regales her with a tale of his most recent case, that of a long lost Mark Twain manuscript. Dennis' company has decided to insure the rare find for $5 million after it's authenticity is confirmed by a leading Twain expert, Professor Chandler Fitzpatrick. Dennis is certain something is wrong, however, when he sees that one of his former associates, Lawrence Erlich, is behind the deal. When Dennis' friend and document expert Constantin Stavros is found dead, he also has a murder to solve.
