# Box 13: Round Robin

A mysterious package arrives at DanHolliday's office—but this time, the puzzle box itself becomes the weapon. When a desperate woman bursts through his door with a cryptic warning about a "round robin" of blackmail letters circulating through the city's elite, Holliday finds himself racing against time to intercept each note before it reaches its destination. With each sealed envelope, a new threat emerges from the shadows, and the private investigator must navigate a labyrinth of lies, hidden identities, and double-crosses to uncover who's orchestrating this sinister game. The tension crackles through every line of dialogue as Holliday's quick wit and sharper fists collide with an adversary who seems to anticipate his every move.

*Box 13* arrived on radio in 1948 just as Americans were rediscovering the thrill of hard-boiled detective fiction on the airwaves. Starring Alan Ladd in the titular role—one of his rare ventures into radio before his film career eclipsed all else—the show captured the post-war appetite for morally ambiguous heroes operating in the shadows of urban America. The series, produced by Jaime del Valle, earned praise for its snappy dialogue and intricate plotting, with scripts that reminded listeners why radio drama remained the most intimate medium of suspense. *Box 13* proved that you didn't need to see danger to feel its cold breath on your neck.

Tune in now and let yourself be transported to that smoky office where danger arrives in the most unexpected packages. Dan Holliday's next case is waiting—and in *Round Robin*, even the most careful plans can unravel with a single letter.
