Dread Journey 

A starlet on a transcontinental train fears her director may be trying to kill her in this novel by Mystery Writers of America Grand Master Dorothy B. Hughes. Four years after she arrived in Los Angeles, Kitten Agnew has become a star. Though beautiful and talented, she’d be nowhere without Vivien Spender: Hollywood’s most acclaimed director—and its most dangerous. But Kitten knew what she was getting into when she got involved with him; she had heard the stories of Viv’s past discoveries: Once he discarded them, they ended up in a chorus line, a sanatorium, or worse. She knows enough of his secrets that he wouldn’t dare destroy her career. But he may be willing to kill her. On a train from Los Angeles to Chicago, Kitten learns that Viv is planning to offer her roommate a part that was meant for her. If she lets him betray her, her career will be over. But fight for the part, and she will be fighting for her life as well.
