When a fellow train passenger is murdered right in front of her eyes, newlywed Ella Westin thinks it's great that all the suspects are trapped with her. But when she can't check out backgrounds or confirm motives - or lack of - she soon finds herself in over her head.

Then an unthinking Joe seems more determined to sabotage Ella's efforts than the murderer. Will she be able to solve the case before a second death occurs? Did the murderer engineer too good a crime for even Ella's skills? Can she track the criminal or will she be derailed before she can put her plan in motion? If the couple survive, is this just the beginning of a toxic relationship?

This is the third story in the Ella Westin Mysteries.
