Deadly Collection
(2026)(The third book in the Track and Tails Mystery series)
A novel by Hailey Hartley
When assistant conductor Rachel Donovan boards the luxurious Cascade Express for its overnight run to Grandview Heights, she's looking forward to a smooth journey. But when a prominent coin dealer is found dead in the dining car during breakfast service, Rachel and her scrappy Border Terrier, Tank, find themselves at the center of a murder investigation. The victim's prized Byzantine gold coin has vanished, and everyone on board seems to have a secret worth hiding.
As the train sits stranded at a remote station, Detective Brennan realizes this wasn't a natural death—it was carefully planned murder by poisoning. With Tank's keen nose uncovering hidden evidence and Rachel's eye for detail piecing together the puzzle, they discover the killer staged the crime to frame an innocent passenger. But the deeper Rachel digs, the more personal the case becomes. When she learns the prime suspect is someone from her own past, she must choose between family loyalty and the pursuit of justice.
Racing against time as passengers grow restless and the killer grows desperate, Rachel and Tank must expose the truth before the Cascade Express reaches its final destination. In a world where obsession can turn deadly and greed knows no bounds, sometimes the most dangerous journey is the one that forces you to confront the darkness in those you once trusted. Can Rachel prove that a coin—no matter how rare—is never worth a human life?
