The Queer Affair at Kettering is a 1940 Australian radio drama by Max Afford starring his detective hero Jeffrey Blackburn and his wife Elisabeth.

[4] Afford was asked to write play quickly after the success of the earlier Jeffrey Blackburn serial Grey Face.

[5] As with The Mysterious Mr. Lynch and Grey Face the two leads were played by Peter Finch and Neva Carr Glynn.

[10] According to a press release, "Elizabeth Blackburn took husband Jeffery — much against his will — down to Kettering Old House, recently rented by those inveterate practical jokers, Sally and Jim Rutland.

"[11] Afford adapted the script into a 1948 short story called The Vanishing Trick which appeared the magazine Detective Fiction.
