Ominous star

After being jilted by her fiancee in Idaho, our heroine, Mary Turner, moves to downtown New York City to rebuild her life. In New York, Mary works in a bookstore where she befriends an older gentlemen customer, Charles Sheridan, who runs a nearby antique store. They develop a platonic friendship and begin having evening drinks and long conversations at his apartment. He deeds her a country cottage and changes his will to provide her a monthly income after his death. Tragically, he is murdered shortly after and Mary becomes a prime suspect in his death. Will Mary be charged for a crime she didn't commit? Can she find the clues that support her innocence? Is the murderer planning to kill Mary too? And, of course, will she find love with a fellow suspect in the Big Apple?
