At close to midnight in the Union Station baggage room, the air is hot, still, and thick. The eleven forty-five Golden State Limited to Los Angeles is approaching rapidly when the baggage handler, Alfred Brody, notices a stray hound dog sniffing around one of the steamer trunks. The horrific discovery of a body inside the trunk can mean only one thing: there's a murderer among them.

The young woman was certainly murdered, but who did it, and why? Suspects and motives abound as Private Detective Mason Adler investigates. He soon realizes that nothing, and no one, are what they seem to be as he races to uncover the truth and bring the real murderer to justice without becoming the next victim.
