Movie star Alan Ladd played Dan Holiday, a former newspaperman turned mystery novelist and adventurer. To gain ideas for his books, Holiday placed an ad in the Star-Times newspaper: "Adventure wanted - will go anywhere, do anything - write Box 13, Star-Times." It wasn't long before his post office box became jammed with adventure offers galore. The stories follow his escapades when he responds to the letters.

Holiday always had more adventure than he had originally sought, because those who responded to his ad never revealed all of their glorious, unusual, and sometimes sinister details until they met in person and the adventure had already begun. Holiday's scatterbrained secretary, Suzy, played by Sylvia Picker, added touches of humor to this mystery-adventure and its nail-biting story lines.

Box 13 was produced by Mayfair Productions, a company run by Alan Ladd and Richard Sandville. In addition to producing Box 13, Ladd also wrote some of the scripts.

Included are these 12 exciting episodes: "Hot Box" (26 Dec. 1948), "The Better Man" (2 Jan. 1949), "The Professor and the Puzzle" (9 Jan. 1949), "The Dowager and Dan Holiday" (16 Jan. 1949), "Three to Die" (23 Jan. 1949), "The Philanthropist" (30 Jan. 1949), "Last Will and Nursery Rhyme" (6 Feb. 1949), "Delinquent Dilemma" (13 Feb. 1949), "One One Three Point Five" (20 Mar. 1949), "Dan and the Wonderful Lamp" (27 Mar. 1949), "Tempest in a Casserole" (3 Apr. 1949), and "Mexican Maze" (10 Apr. 1949).
