The cover image to the right was the original one used on the dust jacket in 1934, and seems to me to be a good likeness of portly and avuncular Mr Parker Pyne.
This title is a collection of 12 of the 14 short stories that Agatha Christie wrote that featured Mr Parker Pyne.
The connecting thread between the stories is Mr Pyne's advertisement at the top of the Agony column of the respectable newspapers:
Mr Pyne's solution for each of the people who consults him is individual and very varied in the fees that he charges. The first 6 stories are set in England while in the last 6 stories Mr Pyne is on holidays travelling first on the Simplon Express, and then to some of Agatha Christie's favourite places in the Middle East such as Baghdad, the Nile, Shiraz and Delphi.
Many of the 12 stories had been individually published in the period 1932-4 but the overall the effect of the collection is like an episodic novel. Wikipedia gives you a lot more detail for each story than I am going to give here. You can also get some details of their publication history.
Mr. Parker Pyne states quite clearly that he is not a detective but 'a heart specialist'. Deception, accomplices and manipulation are all part of his method of operation and he works to cure unhappiness more frequently than to investigate crime.
- The Case of the Middle-Aged Wife, apparently unpublished earlier
Mrs Packington consults Mr Parker Pyne because her husband George has fallen for a young girl from the office. I was interested to meet Miss Lemon, whom I have always associated with Hercule Poirot, in this story.
- The Case of the Discontented Soldier, August 1932
Recently returned from East Africa Major Wilbraham finds London life very tame. Mr Parker Pyne not only creates adventure for him, he sends him on a treasure hunt. In this story Mrs Ariadne Oliver makes a fleeting appearance - another character I have always associated with HP.

This is not the story that features Hercule Poirot, but one about a lady who dies of poisoning.
- The Oracle at Delphi, April 1933
Mr Parker Pyne finds someone who is impersonating him, and takes great exception, in the process foiling an attempt at extortion.
My rating 4.2
Mr Parker Pyne appears in 2 other short stories, one of which I have already read in Problem at Pollensa Bay published in 1935. Interestingly in this short story he is referred to as Christopher Parker Pyne, although in PARKER PYNE INVESTIGATES he is always referred to as J. Parker Pyne. The other story is one I haven't yet read The Regatta Mystery published in 1939.
