Gallows Court by Martin Edwards is the first book of the Rachel Savernake mystery series set in 1930 London, with flashbacks to 1919 on Gaunt Island in the Irish Sea.
Daughter of Judge Lionel Savernake ("Savernake of the Scaffold"), Rachel grew up on isolated Gaunt Island with cousin Juliet Brentano. Juliet's diary reveals "Everyone knew that, if Rachel was in a temper, someone or something must suffer." After Rachel was scolded by a governess, the woman's beloved pet dog disappeared; a few days later, Rachel "found" its bloodstained collar on the rocks below the cliff. When the governess fled, Rachel smirked to Juliet "that's how to kill two birds with one stone". When Juliet's parents disappear, she's convinced Rachel murdered them.
The Judge died; Rachel is now extremely wealthy. She moves to luxurious Gaunt House in London, with a few trusted loyal servants from Gaunt Island. Trueman is her bodyguard and the chauffeur of her Rolls Royce Phantom, Henrietta her housekeeper, Martha her maid.
From the start, a delicious atmosphere of menace pervades: "Long years spent on a small island had accustomed her to sea frets...the winter mists drifting in from the water, rippling like gauze curtains, draping the damp landscape. A London particular was a different beast - sooty, sulphurous, and malign, as capable of choking you as a Limehouse ruffian."
Rachel has scores to settle. She begins a series of intricately planned, perfect murders. She uncovers who really killed Dolly Benson (The Chorus Girl Murder); he "commits suicide". She visits the murderer of Mary-Jane Hayes; his corpse is discovered in a locked room. She's not done yet...
Jacob Flint, reporter for the Clarion newspaper, receives anonymous tips to find the victims, scoops the stories. Jacob is convinced Rachel is involved, but she rebuffs him...at first. He persistently, carefully follows up evidence, researches history, looks for connections in the past. He learns of the Gambit Club, a group of wealthy influential men, formed/led by the Judge in Gallows Court, ostensibly to play chess.
Jacob does not accept the easy, obvious crime solutions. Scotland Yard is under pressure to close cases; he's after the truth. When he interviews a victim's sister, she accuses that reporters just print sensational stories, not truth. He counters: "I happen to believe that the truth is a good story". Unlike other reporters, he empathizes with victims' family and friends: "You imagined you had all the time in the world to see each other in the future."
Clarion's chief reporter Thomas Betts was following up clues when he "met with an accident". Clarion editor Gomersall obliquely warns Jacob that pursuing Rachel and her past is dangerous. "The editor measured his words with the care of a pharmacist dispensing henbane to a discontented spouse."
Rachel seeks out powerful, dangerous men in the Gambit Club, fearlessly taking risks: "The danger is what makes life worth living". When she meets William Keary (famous/wealthy/smooth-talking Irish actor) she reflects "his smile showed a lot of teeth. They resembled small, sharp tombstones." Rachel drinks vintage Burgundy, "the color of blood". Her motto: "When I play, I play to win".
Clarion editor Plenderleith told Jacob "Levi Shoemaker is the smartest enquiry agent in London, by far the most expensive." Rumor has it Levi was hired by Rachel. Levi eludes contact, but Jacob finally confronts him. Levi warns "Rachel Savernake is the most dangerous woman in England".
Jacob exchanges information with contacts at Scotland Yard, usually over drinks or meals at a pub. Summoned to a remote cabin to meet a contact, Jacob witnesses several murders. This time, he can't write the story. Rachel begins inviting Jacob to events...where he witnesses dramatic perfect murders.
The plot twists as secrets are revealed by Juliet's diary entries and from Jacob's diligent research. Suspense builds to a surprise confrontation, a final settling of scores. A Golden Age style mystery with a twist: a fearless, invincible killer protagonist, committing perfect crimes, getting away with it.
I enjoyed reading the Lake District mystery series; I enjoy the Harry Devlin mystery series too, but to me, Gallows Court is the most gripping and intriguing yet. I look forward to the sequel, Mortmain Hall.
