Box 13 was a syndicated radio series starring Alan Ladd as newspaper reporter-turned-novelist Dan Holiday. Holiday obtained ideas for his novels through an ad he placed in the Classified section of the Star-Times newspaper. It read:

“ADVENTURE WANTED! Will go anywhere, do anything. Write BOX 13, c/o Star-Times.”

This ad brought the usual assortment of crackpot responses, but more often than not brought Holiday more trouble than he bargained for, since he never found out the pertinent details until after he’d met the clients. He never charged a fee for his “services”, because he was paid very well for the stories he wrote.
