At the encouragement of his publisher, famous mystery writer Kent Bronwyn is a guest speaker at a comic book convention in San Diego, California. It has been a long tiring day and he is looking forward to sleeping on the train back to Los Angeles. Things don't go as planned as he has missed the train he had a reserved ticket for and he now waits for the last train among hundreds of costumed convention-goers called Cosplayers. It's like being in the midst of a four-color comic book come to life. Bronwyn enjoys watching them all interact, but he's more interested in getting off his feet once the train arrives. Once aboard, he hardly has time to rest when one of his fellow passengers ends up murdered. With the encouragement of young fans of his mystery novels he reluctantly must solve the crime... which is no easy task as all the suspects are in costume, and no one is who they claim to be.
The first in the Kent Bronwyn mystery series, this story pays homage to the great comic book conventions of Southern California, the Cosplayers in attendance, and the crowded train they ride to go home.
