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.[1] 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.
The play is notable for starring Francis L. Sullivan in the part of Hercule Poirot, reprising his portrayal of the character following his success in the stage play Black Coffee in 1930.
The script of the play is published by Samuel French, separately, and in the collection Poirot Double Bill with another short play "Yellow Iris".
Critical response
A three-line review in The Observer of 20 June 1937 by "E.H.R" stated that the first performance was "excellently done".[2]
