Picking up where Frozen Heat left off, top NYPD Homicide Detective Nikki Heat pursues the elusive former CIA station chief who ordered the execution of her mother over a decade ago. For the hunt, Nikki teams once again with her romantic partner, Pulitzer Prize-winning investigative journalist Jameson Rook, and their quest for the old spy and the motive behind the past murder unearths an alarming terror plot-which is anything but ancient history. It is lethal. It is now. And it has already entered its countdown phase.
Complicating Heat's mission to bring the rogue spy to justice and thwart the looming terror event, a serial killer begins menacing the Twentieth Precinct and her homicide squad is under pressure to stop him, and soon. The frightening murderer, known for his chilling stealth, not only has singled out Nikki as the exclusive recipient of his taunting messages, he then boldly names his next victim: Detective Heat.

- In one scene, where Rook spots a serial killer nearby a stone Castle in a New York City park, he calls Nikki and when she asks where the killer is, he simply answers "Castle."
- Periodically throughout the book, Rook takes meetings with Hollywood film producers interested in making one of his articles about Nikki into a movie, just like Heat Wave (Novel) was made into a movie. In one such scene, producers mention the possibility of casting "Nathan, if he's available."
- The serial killer who targets and taunts Nikki is a combination of Scott Dunn from Boom – (Part 2) and the Triple Killer from 3XK and Probable Cause.
- The bioterror plot is reminiscent of the dirty bomb plot from Setup and Countdown

- Throughout the story, Bart Callan tries to recruit Beckett to work more closely with him and the Feds on her mother's case, just like Jared Stack recruited Beckett to work for the federal government. His attempts at flirting with her, are a reminder of how Detective Inspector Hunt from The Limey and Ioan Gruffudd from The Squab and the Quail made plays for Beckett, even though she was either interested in or dating Castle.

References in episodes
- In Watershed (5x24), Castle believes that Beckett was "leaving him alone" for a couple of days to finish Deadly Heat when she went to secretly interview with the AG's office. In the same episode, Castle tries to distract Alexis by showing her two different proposals for the cover of the book, the red one that became the actual cover, and a green one. ("I like the green one, but it kind of looks like a giant green lizard's attacking the city. Which is cool, but it's not what the book's about.")
- In Valkyrie (6x01), Castle returns from from an exhausting west coast book tour for Deadly Heat with a cutout of himself under his arm.
- In Number One Fan (6x04), the book features in one of the telephone questions Emma Riggs asks Castle to prove that it's really him. ("In Deadly Heat, what's Douglas Sandman's nickname?")
