This is a 1910 mystery novel by English author Alfred Edward Woodley Mason (A.E.W. Mason) and is the first book in his Inspector Hanaud series. The setting is in late 1900s in the spa town of Aix-les-Bains in southeastern France, across the border from Geneva. It is a police procedural book and is very tightly structured. All the loose ends are tied up in the end and all clues are explained. Mason’s goal was to create a fictional detective who is the exact opposite of Sherlock Holmes. His Inspector Hanaud is “stout and broad-shouldered” and looks like a “prosperous comedian” and a Newfoundland dog; just the opposite of the tall and sleek Sherlock Holmes. Also, Hanaud is a famous professional detective with the Paris Surete (the French police), unlike Holmes, a private consulting detective. Some have suggested Hanaud is a prelude to Agatha Christie’s famous Hercules Poirot. Similar to the Poirot (who will not appear until a decade later in 1920 with The Mysterious Affair at Styles), Hanaud is very smart and vain, and is not afraid to say so. In this book, for example, Hanaud describes himself as “I, the great, the Incomparable Hanaud”, just like Poirot does so often. Similar to Holmes and Poirot, Hanaud also has his Watson, in the person of a rich retired businessman Julius Ricardo. Hanaud is also into forensics. In this book, he used various forensic technics like fabric comparison, hair sample, and soil sample and shoe imprint to help him solve his case.
The book is quite well plotted and is written with an interesting structure. It starts with the commission of the crime, the detection by the detectives involved, and the case was solved about 65% into the book. The rest are multiple chapters told from the perspectives of the criminals and a surviving victim and starts from the genesis of the plot until the crime’s commission. Overall, I think this two-part structure is an interesting one. It is similar to (but a big improvement from) the one used by Emile Gaboriau in Monsieur Lecoq and by Arthur Conan Doyle in A Study in Scarlet, where the crime and its solution are dealt with in the first half of the book, and the old history that led to the commission of the crime is dealt with in the second half as if it is a totally separate story.
Spoiler Alert. This is the story of how a master criminal plotted an ingenious scheme to rob and murder a gullible and naïve woman and tried to frame a young pretty girl for the crime. Villa Rose is the name of the villa in Aix-les-Bains where the murder victim Madam Camille Dauvray was staying in. Madam Camille Dauvray was a rich old lady who was very impressionable, kind and superstitious. For years, she has lived with her maid Helene Vauquier. Recently, Dauvray ran into a young, pretty, poor and destitute English girl called Celia Harland in Montmartre in Paris. Celia was a skilled impromptu performer and knew how to play a séance medium very well. Dauvray, who was very much into fortune-telling and squandered a lot of money on fortune-tellers, became interested in séance and took Celia in as a companion to live with her. Unlike the fortune-tellers who tried to take advantage of Dauvray financially (and paid kickbacks to Vauquier), Celia did not trick Dauvray for money although Dauvray did dress Celia very well and showered her with expensive jewelry. That made the old servant Vauquier very jealous, feeling she has been replaced by Celia. Vanquier, who is very smart, came up with an ingenious plan to rob the extremely valuable jewelry collection of Dauvray and frame the robbery and murder of Dauvray on Celia. Vanquier enlisted the help of Harry Wethermill, a dashing young inventor who looked rich but is actually broke. She also got a family of three career criminals from nearby Geneva to help (mother Jeanne Tace, son Hippolyte Tace and Hippolyte’s wife Adele Tace). Vanquier also invented a very complicated setup to frame Celia. On one fateful Tuesday evening, Adele Tace, who has become a recent acquaintance of Dauvray and pretended to be a séance skeptic, was invited by Dauvray to Villa Rose so Celia can demonstrate her skill as a medium in a séance. Vanquier and Adele took that opportunity to tie Celia up, and then Wethermill showed up and strangled Dauvray for the gang. After that, they opened Dauvray’s safe and was shocked to find that her jewelry collection was not inside. At that time, a policeman stopped by on his routine beat, and that scared the criminals to leave the premises. They kidnapped Celia to Geneva, thinking she knew where the jewels were hidden. In the meantime, Vanquier played a victim and was tied up, waiting to be discovered by the police. The criminals did a good job laying out various clues that led the police to initially believe Celia was behind the scheme and it was her who killed Dauvray and has now fled with the jewelry. Soon, Inspector Hanaud (who was on vacation in town) was called in to help. He soon realized the crime was planned by someone with brain and daring. Not long thereafter, Hanaud discovered the jewels were actually hidden below some secret floorboard in Dauvray’s bedroom and the criminals have failed to find them. At first, the evidence look very black against Celia. She was the one who disappeared, she was the one who told the chauffeur to take the night off, her shoe prints were outside the house, and she was identified as the one who bought the rope that was used to strangle Dauvray. She was initially the focus of the investigation.
By examining the car of Dauvray (which was found stolen and later recovered), Hanaud correctly surmised that the criminals have fled to the nearby Geneva and he used Ricardo’s name to advertise for information on Celia with a huge reward. When a witness called Marthe Gobin came forward, she was murdered by Wethermill before she got a chance to tell her tale. Fortunately for Hanaud, she also wrote a letter to Ricardo which told everything she saw, which led Hanaud to raid the Tace house in Geneva and rescued the kidnapped Celia. Soon after, the whole plot was unraveled and every planted clue against Celia that initially led police to believe Celia was the murderer was discredited. All the criminals were subsequently caught.
