Double trouble with Susan Ryeland

by Ben Soton

Marble Hall Murders by Anthony Horowitz, Penguin Cornerstone 2025; pbk 592 pp, rrp £9.99

This is the third in a series of novels featuring Susan Ryeland; the others being Magpie Murders and Moonflower Murders, both of which have been televised.  Susan Ryeland is arguably a modern Miss Marple; instead of a spinster living in a quaint West Country village she is a career woman working as an editor for a publishing company.  Like Miss Marple she has never been married and at fifty-five unlikely to have children; instead she appears to be constantly in and out of unsuccessful relationships.  
All three books are in effect two novels in one.  One being a murder set in the present day and the second, the novel that Ryeland is editing set in the 1950s and featuring the fictional detective Atticus Pünd. 
Pünd, a refugee from Nazi Germany, is a kind of post-war Poirot. And the essence of all three books is that the fictional novel contains the secret to the murder set in the present day. 
In Marble Hall Murders an up-and-coming author, Elliot Grace, has been commissioned to write Pünd’s Last Case.  Grace, a troubled young man with a tainted past uses the novel to expose his grandmother’s murder.  As with the previous books the characters in the Punt novel mirror with those in the present-day story.  
Meanwhile we see the return of murderer, Charles Glover, from Magpie Murders; although this time incarcerated in Belmarsh Prison wearing a grey tracksuit instead of Saville Row attire.  Glover makes the comment that prison is easier for men who’ve been to public school.  
A feature of the book (or book within a book) is that the author effectively reviews the Pünd novel as she narrates the modern-day story.  She regularly asks questions related to matters of historical accuracy and often what would appear to be minor issues. This taking the reader into the world of publishing.
Meanwhile although I established the identity of the murderer in the Pünd novel (I am no detective) the reader is kept guessing as to the identity of the killer in the present-day story or perhaps even questioning if there was a murder at all; the victim being in her eighties and suffering from a heart condition.       
Moonflower Murders is a story of revenge and anger spanning generations as well as different time periods.  Ryeland searches the novel for anagrams and cryptic clues as to the killer’s identity.  I understand the book will soon become a television series. I look forward to watching it.  But Horowitz leaves us in an element of suspense as to whether there will be another Atticus Pünd /Susan Ryeland novel.
