By my reckoning Agatha Christie wrote 157 short stories, published in a number of collections. Wikipedia records that she wrote 153 short stories, published in 14 collections in the UK and in the US. Some stories were published under different names in the US Collections.
I’ve compiled this list from the list of short stories on the Agatha Christie Site. I may have included duplications which could account for the difference in numbers. As I work through the stories I will amend the list as necessary.
The titles shown in bold are stories I have read and I have indicated the collection in which they appear – some appear in more than one collection and I have only recorded the ones I have read. The links are to my posts on the collections.
