Box Thirteen was one of the best things Alan Ladd ever did. It was a high quality show which relied on his charisma and talent rather than a large budget. Box 13 actually began running on KNX in Los Angeles on Sunday, May 16, 1948 at 7pm replacing "Escape". A clueless acquaintance wants Dan Holiday (Alan Ladd) to fly to Mars with him in his home made rocket and has a ticket to a radio broadcast. Sylvia Picker makes her first appearance as Holiday's scatterbrained secretary, Suzy. Sylvia Picker was born on April 11, 1909 in New York City, New York, USA. She was an actress, known for Lucky Devils (1933), The Devil Bear (1929) and Sterling's Rival Romeo (1934). She was married to Grant Garett. She died on September 25, 1981 in Los Angeles, California, USA.
