Rachel Savernake is a criminologist enthusiast, she is also the daughter of a now-deceased judge who ended up losing his mind after he sentenced a man to death for a crime he didn’t commit. Rachel lives in a large house with her trusted staff and helpers the Trueman’s.

The book opens with Rachel trying to save a man she calls a ghost. Author Gilbert Payne, who faked his death a few years ago and is now pretending to be Bertram Jones, is on the funeral train having returned from Tangiers for his mother’s funeral. Rachel warns him that there are people on the train looking to kill him and that she will protect him but she wants to know why he faked his death and why someone wants to kill him.

Gibert Payne refuses to heed her advice and help and is found dead on the train tracks later that day. Civil servant Reggie Vickers was the one who told Rachel about Gilbert as he was his friend and had hoped to save his life. Reggie is now running scared from not only people warning him to keep his mouth shut but from Rachel and her questions as she believes he knows more than he is telling.

Journalist Jacob Flint has been following the case of Clive Danskin, accused of murder, the case seems to be open and shut with the verdict set to be guilty, that is until a witness comes forward at last minute and he is set free. Criminologist Leonora Dobell is at the trial and talks to Jacob. She knows that he is on friendly terms with Rachel and wants him to pass on a message to her, she would like a meet to discuss a murder. Leonora lives in Mortmain Hall.

Mortmain Hall is a mystery/sleuth book set in 1930s England. Rachel Savernake is quite a reclusive young woman who spent most of her time in a big house in the country looking after her sick father. Now he has deceased she has decided to use the skills that she has learned over the last few years following the books on criminology written by Leonora Dobell.

The book features many subplots from different cases that all come together in a kind of murder mystery weekend setting at Mortmain Hall. The book is completely fascinating and I just couldn’t put it down. Rachel is a phenomenal woman who is headstrong and is a match for any man of the time period. She is exceptionally wise, ruthless, and quite scary to some.

I love historical detective books and this is up there with the best. The plot draws you in and has you trying to analyse everything that is happening and wondering how they are all joined together and the writing is sublime. I was completely gripped from the opening chapter to the last. If you love sleuth books then this is a must-read.

Agatha Christie is the most successful detective novelist in history. In fact, she is the all-time bestselling novelist in any genre. This isn’t luck or just a matter of good marketing. There is a timelessness about her mysteries, and a universality about the character types who inhabit her fiction that gives the stories an appeal that is global and enduring.

Christie inspired my love of the genre, and you can trace her influence in several of my novels, including Mortmain Hall, which is (among other things) a country house mystery in which the great detective gathers the suspects in the library to reveal whodunit. She was a founder member of the legendary Detection Club in 1930 and for the last twenty years of her life she was the Club’s fourth President. The Club is celebrating its 90th birthday this year and as the eighth and current President, I’m thrilled to be following in her footsteps.

Here are my ten favourites among her novels.

The Murder of Roger Ackroyd

Hercule Poirot’s retirement from detection didn’t last long. He’s growing vegetable marrows in a small English village when he’s prompted to investigate a murder in collaboration with a local doctor. Controversial in its day, this is the detective novel that shows you really do have to suspect everyone.

The Murder at the Vicarage

Miss Marple’s first full-length case is another classic village mystery. Can the genteel elderly spinster outwit the official police as well as a cunning murderer? You bet she can.

Peril at End House

Christie specialised in stories in which the ‘least likely suspect’ proves to be the murderer. Her skill at misdirecting the reader is seldom more evident than in this clever mystery, set on the English Riviera.

Murder on the Orient Express

One of the most famous detective stories of all time, this train-based mystery defeated the legendary private eye writer Raymond Chandler, who complained that ‘only a half-wit could guess it.’ He shouldn’t have been so grumpy. All the clues are there, if only you can spot them.

The ABC Murders

A sequence of killings linked by the alphabet seems to be the work of a deranged killer who is determined to taunt Hercule Poirot about the crimes. The little Belgian sleuth rises to the challenge in one of the most influential of all detective novels.

Death on the Nile

Christie’s love of the Middle East meant that she often used it as a setting for her stories. This classic cruise mystery involves a tangle of romantic relationships which conceals the truth to a sinister murder plot. Fortunately, Hercule Poirot is on board…

Five Little Pigs

Poirot investigates a possible miscarriage of justice. Was Caroline Crale, who died in prison, really the killer of her artist husband? This is a classic cold case mystery with a limited pool of suspects but Christie still manages to spring a surprise in a chilling finale.

A Murder is Announced

A strange advertisement in a local newspaper is the starting point for a baffling mystery. Miss Marple is confronted by a determined killer and an ingenious murder plot. Christie’s use of a typographical clue in the text is especially neat. Of course, in the end our heroine prevails…

Curtain

This dark if low-key story marks Hercule Poirot’s final appearance as he returns to the scene of his first recorded case and reunites with Captain Hastings. The plot is one of Christie’s finest, and most chilling. Surely her most under-estimated novel.

And Then There Were None

Often imitated, never bettered, this is a tour de force of detection – without a detective. Ten people are invited to a small island. One by one they are killed. What is the motive for the crimes and who is responsible? This is surely the finest of all detective novels in the classic tradition.
