Mystery of the Baghdad Chest’ (January 1932) were published in 1923/24. All the Poirot short stories after 1932 feature Poirot alone. No notes for any of those early stories survive and where Christie refers to them in the Notebooks, it is only as a reminder to herself of the possibility of expanding or reusing them. In many ways ‘The Incident of the Dog’s Ball’ is similar in style, setting and tone to many others dating from the early 1920s and published in
In Notebook 30 it is included in a list (illustrated on the jacket of this book) which may help us to establish more accurately its date of composition:
Ideas
A. Dog’s Ball
B. Death on the Nile
C. Strychnine absorbed through skin?
D. Double Alibi e.g. A and B murder C but—A is accused of trying to murder B at same time.
E. Figurehead woman. Man back from Africa.
F. Second Gong elaborated
G. Mescaline
H. Illegitimate daughter—apomorphine idea?
Ideas to be incorporated
Brownie camera idea
Brooch with AO or OA on it AM. MA
If we apply some of Poirot’s own methods we may be able to arrive at a timetable.
There are a number of immediately recognisable stories here:
Unlike Item F on the list, ‘Second Gong elaborated’, there is no mention of elaboration in connection with ‘Dog’s Ball’, lending support to the theory that it did not then exist as a short story.
In the Christie Archive there are two letters from her agent Edmund Cork. One, dated 26 June 1936, acknowledges receipt of a revised version of
It is not unreasonable to suppose that the writing of
In the change from ‘The Incident of the Dog’s Ball’ to
General Plan P. receives letter—he and H—he writes—then he tears it up—No, we will go—Market Basing —The Lamb
Market Basing is commonly assumed to bear more than a passing resemblance to Wallingford where Agatha Christie lived. She bought her house there in 1934 and this may account for the change of setting for the novel. There is evidence for this in the reference to The Lamb, a Wallingford pub, in Notebook 63. This is, admittedly, conjecture but as Poirot would say, ‘It gives one furiously to think, does it not?’
Miss Matilda Wheeler writes to Poirot on 12 April, a Wednesday, according to Poirot’s exposition: ‘Consider the dates, Hastings’ (section v). The 12th of April fell on a Wednesday in 1933.
So we may conclude that ‘The Incident of the Dog’s Ball’ was
written, in all likelihood, in 1933.
Agatha Christie was now a household name. By the mid-1930s and
Her production of short stories had decreased from the multiple appearances of earlier years—27 in 1923 and 34 in 1924—to a mere half-dozen in 1933 and seven the following year. As she said when she refused to contribute to the Detection Club’s collaborative novels, ‘the energy to devise a series is much better employed in writing a couple of books’. She may well have thought the same about this short story and decided to turn it into a complete new Poirot book.
The Edmund Cork letter referred to above, dated 26 June 1936, acknowledges receipt of a revised version of
This not-offered-for-sale theory may also account for the major oversight involving the dates within the story. In section i Poirot says ‘No, April the 12th is the date [on which the letter was written] assuredly’ but in section iv he refers to August as the month when Miss Wheeler wrote the letter. An agent and/or an editor would surely have noticed a mistake of this magnitude, and one so germane to the plot.
In conclusion, it is entirely possible that ‘The Incident of the Dog’s Ball’ was written in 1933 and never offered for publication but, instead, transformed, in 1935/36, into the novel
