The play is unique in that it is the only instance of Christie adapting one of her works for television, a medium she later came to dislike. It was broadcast live from Alexandra Palace as part of the programme Theatre Parade. The broadcast took place at 3.35 pm and lasted for twenty-five minutes. It was then repeated the same evening at 9.40 pm and lasted for twenty minutes. Theatre Parade usually showcased successful stage shows of the time but in this instance presented an original work.
The play was only broadcast in the London area as this was the only part of the UK that could receive television transmissions at this time. Neither transmissions were recorded for future viewing as television recording equipment had not been invented at this point in time.
A three-line review in The Observer of 20 June 1937 by "E.H.R" stated that the first performance was "excellently done".
