How to Read the Capital Mysteries Series

For young readers diving into the adventures of KC Corcoran and Marshall Li, navigating the series is straightforward. While the books are largely episodic, it is highly recommended to read them in publication order. This is because the characters' lives develop over time—most notably in A Spy in the White House (Book 4), where the President marries KC's mother, Lois, making KC the First Daughter. This new status changes how the duo accesses secure areas in Washington, D.C. for their future investigations.

The A to Z Mysteries Crossover

If you want to experience the ultimate crossover, you should also read A to Z Mysteries Super Edition #3: White House White-Out (published in 2008). In this special crossover book, the detectives from Ron Roy's main series—Dink, Josh, and Ruth Rose—visit D.C. and team up with KC and Marshall to solve a case involving a snowstorm, the President's dog, and a plot to kidnap KC. For the best experience, read this super edition after Book 10 (The Election-Day Disaster) to align with its release timeline.
