Hickory Dickory Dock by Agatha Christie was first published in 1955. It’s a Poirot book.
When Poirot’s normally perfect secretary Miss Lemon makes three mistakes in one letter that she has typed for him he realises that there is something seriously wrong with her. It turns out that Miss Lemon’s sister is having problems at her work. She is a matron at a hostel for students, and things have been disappearing. It seems that there’s a kleptomaniac living within the hostel, a strange conglomeration of items have gone missing. Miss Lemon’s widowed sister is worried, as is Miss Lemon. Obvioulsy Poirot has to investigate, and things take a much more serious turn when one of the students is found dead.
This is a book that I’ve had in the house for years, unread. That is probably because I much prefer the Miss Marple books to Poirot, of course this book is still a good read.
I might be strange but it’s the Art Deco style of the Poirot episodes that I appreciate most about them, although there’s not quite enough of it, in my opinion. What is your preference, Marple or Poirot? If Marple which one? There are quite a few to choose from, all good but Joan Hickson is my favourite.
I’ve just checked and it’s over ten years since I read an Agatha Christie book. How did that happen?
Murder Must Advertise by Dorothy L. Sayers was first published in 1933. My edition is a Hodder reprint from 2016.
Whose Body? by Dorothy L. Sayers was first published in 1923. It begins with Lord Peter Wimsey getting a phone call from his mother. She tells him that Mr Thipps the architect who is working on her local church’s roof, has discovered the body of a man in his bath. The body is naked apart from wearing a pair of pince nez. When Peter goes to investigate he realises that the corpse is supposed to be the wealthy businessman Sir Reuben Levy who has gone missing. It bears a resemblance to Sir Reuben, but Peter isn’t fooled.
Hop Scot by Catriona McPherson (Last Ditch series) was published by Severn House (Canongate Books) in 2023. I picked this one up recently from the New Arrivals shelf in my local library. I enjoyed the author’s previous Dandy Gilver series which is set in the 1920s/30s. This series is contemporary and unfortunately I’ve found it rather late because when I started to read it I realised that this one is sixth in the series, but I don’t think it’s really necessary to read them in order, although I wish I had.
