The Scoop and Behind the Screen are both collaborative detective serials written by members of the Detection Club which were broadcast weekly by their authors on the BBC National Programme in 1930 and 1931 with the scripts then being published in The Listener within a week after broadcast.
The two serials were first published in book form in the UK by Victor Gollancz Ltd in 1983 and in the US by Harper & Row in 1984.
..."[1] The episodes, contributors, transmission and magazine publication details of this serial are as follows (all episodes were transmitted from 9:25 pm to 9:40 pm): In The Listener (and subsequently in the book version), four of the episodes were untitled, the exceptions being the fourth and sixth, which were given the titles In the Aspidistra and Mr Parsons on the Case respectively.
As announced in The Guardian on 2 December 1930, Behind the Screen proved popular enough for the BBC to commission a second serial, this time in twelve instalments.
The book version of the serial (1983) replicates these chapter titles.
