Researcher Karl Schadow has documented that an early weekly series on the Mutual network had eight scripts that Jack Johnstone revised for Suspense under producers Bruno Zirato, Jr. and Fred Hendrickson.

The series was Who Knows? and was a 15-minute program. The list is as follows: 


  • 1961-08-06 Bells (has the full background at the end of its blogpost)

  • 1961-09-17 The Green Idol

  • 1961-10-08 Dreams

  • 1962-01-14 Feathers

  • 1962-02-04 Friday

  • 1962-04-22 The Curse of Kamashek

  • 1962-06-10 Formula for Death

  • 1962-09-30 Devilstone


As noted above, the Bells blogpost has the most details about that Mutual series, the original broadcast dates.

The episodes are now each labeled as "Who Knows?" and can be accessed as a group using this link https://suspenseproject.blogspot.com/search/label/Who%20Knows%3F

We thank Karl for his steadfast support of this project. Read about his work at a blogpost about him by the Library of Congress https://blogs.loc.gov/loc/2018/05/inquiring-minds-bringing-radios-golden-age-back-to-life/
