Murder in the Mist The Gaslight Mysteries

Murder in the Mist

Tis the season of goodwill, and Dickens extends the hand of friendship to a stranded stranger and his nephews for Christmas, with deadly consequences . . .

“The ingenious solution to the mystery makes this the series’ best entry yet. Victorian whodunit fans are in for a treat” Publishers Weekly Starred Review

Wilkie Collins is looking forward to spending Christmas at Gads Hill, Charles Dickens’ Kentish country home, but the festivities are cut short when a body is found on the snowy marshland. Timmy O’Connor was invited to the gathering with his four nephews after a chance encounter with Dickens, but is now dead.

Dickens is convinced the murderer is one of the convicts from a nearby prison ship, but Collins is not so sure. Who was this mysterious and unpleasant stranger from Cork who turned Christmas cheer to fear? With the convicts, guests and even Timmy’s nephews under suspicion, there is no shortage of suspects for such a violent act, but which one of them is a cold-blooded killer?

Reverend Mother series

The Deadly Weed

by Cora Harrison

1920s. Cork, Ireland. Early one morning the Reverend Mother receives news of a deadly fire at the local cigarette factory, a place where she’d been so proud that some of her pupils had been given a steady job. In a city full of poverty, unemployment and political unrest, these ex pupils of hers had surely been blessed with such prospects. Now, though, she is worried . . . What happened at the cigarette factory and why are there rumours circulating that one of her ‘girls’ was responsible?

Inspector Patrick Cashman is under pressure to quickly find the cause of the fire – and identify a suspect – to placate the visiting Lord Mayor and Commissioner and secure his hopes of promotion. Patrick turns to his friend, the journalist and law student Eileen MacSweeney, for help, along with the ever insightful and calm Reverend Mother. From the fog-ridden streets of the slums to the green pastures and prosperity of nearby Youghal, together they begin to unravel a seedy history of greed, ambition and a desire for power.

Review from Publishers Weekly

“A fire at a Cork cigarette factory owned by the Reverend Mother Aquinas’s cousin Robert Murphy sparks Harrison’s stellar 10th 1920s Irish mystery featuring the insightful religious sleuth (after 2022’s Murder in the Cathedral).

“Murphy gave jobs to 10 girls in the school the Reverend Mother oversees, largesse she welcomed as a means for the impoverished children to earn something for their families.

“The fire’s one fatality is Timothy Dooley, the plant’s manager, who had drunk himself into unconsciousness and died of smoke inhalation. Though there were no obvious signs of arson, a witness claims that one of the girls, Maureen McCarthy, stayed behind after her colleagues had left the factory and started the conflagration.

“As Insp. Patrick Cashman investigates, he finds Maureen uncooperative and hostile, and learns that Dooley was once accused of rape. That discovery leads him to expand his circle of suspects to include the rape victim’s father.

“Aided by the Reverend Mother, who rivals Jane Marple in her astute observations of human nature, the inspector narrows in on the truth. A fair-play puzzle matches a vivid evocation of the past. Harrison is writing at the top of her game.”

Reverend Mother series

Murder in the Cathedral 

by Cora Harrison

The Reverend Mother’s investigative skills are called into action again when one of her young pupils is found murdered at St Fin Barre’s Cathedral.

1920s. Cork, Ireland. The Reverend Mother’s Christmas Day festivities are shattered when the protestant bishop of Cork arrives at the convent with terrible news: one of the Reverend Mother’s pupils, the troublesome seven-year-old Edna O’Sullivan, has been found murdered in St Fin Barre’s Cathedral. Furthermore, the cathedral’s archdeacon, Dr Hearn, is also dead after succumbing to a suspected heart attack in the middle of a service.

When it is revealed that both Edna and the archdeacon were poisoned, the Reverend Mother is drawn into another puzzling mystery. Was the boy used as part of an elaborate plot to murder the archdeacon? And if so, why was he willing to risk his life to do so? As she investigates, the Reverend Mother makes a series of disturbing and intriguing discoveries. Can she uncover the truth behind these heinous crimes?

Review from Publishers Weekly


“Set in the late 1920s, Harrison’s outstanding ninth whodunit featuring the Reverend Mother Aquinas (after 2021’s Murder in an Orchard Cemetery) opens with an unexpected visit from Dr. Thompson, the bishop of Cork’s Anglican Church of Ireland.

“Thompson reports that one of the Reverend Mother’s pupils, seven-year-old Enda O’Sullivan, has died. Someone poisoned the communion wine at the Protestant cathedral with cyanide, killing its archdeacon, Dr. Hearn.

“According to the bishop, the Reverend Mother’s ally on the force, Insp. Patrick Cashman, believes that the murderer bribed Enda to put the cyanide in the archdeacon’s cup by giving the boy some chocolates injected with the poison to cover up his crime.

“Given Hearn’s wide unpopularity, the Reverend Mother and the inspector have plenty of suspects to consider in their probe.

“Harrison does a masterly job combining plot and characterization and resolves the puzzle satisfactorily, but the book’s real strength is her heartfelt evocation of the lives of Cork’s impoverished citizens and the Reverend Mother’s dedication to helping them.

This series ranks near the top among mysteries with a religious lead.

Review from Kirkus Reviews

A Reverend Mother, a police officer, a newspaper reporter, and a Jewish doctor extend their long, successful record of solving crimes in Cork in the 1920s.

“Reverend Mother Aquinas has seen the worst of humanity, and nothing surprises her. But the Christmas double murder of an archdeacon of the Anglican Church of Ireland along with one of her most troublesome and downtrodden students makes her very angry indeed. Bishop Thompson comes himself to inform her that Dr. Scher, the police surgeon, thinks that both 7-year-old Enda O’Sullivan and the archdeacon were poisoned.

“Inspector Patrick Cashman and journalist and law student Eileen MacSwiney, two of the Reverend Mother’s most accomplished and beloved students involved in the case, rely on her wisdom to help solve a horrible crime with political implications. Apparently someone had tricked Enda into climbing into the cathedral, putting poison into a chalice, and then eating poisoned candy.

“Though the mischievous Enda had the voice of an angel, neither he nor his mother was popular in the Catholic community, and the Reverend Mother has to use all her influence to arrange a proper funeral. Patrick quickly learns that the archdeacon was disliked by a great many people for a great many reasons but wonders whether any of them are serious enough to kill for.

“Even in an Ireland free of England, members of the old guard still occupy many of the top positions. As a Catholic, Patrick relies on his Protestant assistant for insight. In the end, Dr. Scher’s knowledge of antique silver gives the Reverend Mother the answer.

Plenty of suspects dramatizing Ireland’s religious differences provide an excellent character-driven mystery.

Spring of Hope The Gaslight Mysteries

Booklist review of Spring of Hope

Cleverly plotted, deftly written, with vivid characters, rich period ambience, and gentle humor, Harrison’s latest is sure to please fans of historical mysteries.


Harrison again pairs Charles Dickens and Wilkie Collins as amateur sleuths (following Summer of Secrets, 2021).

London is recovering from the 1858 “Summer of the Great Stink,” which has resulted from human waste flowing into the Thames. The government is determined to find a solution, with the pollution growing deadlier with each passing month.

A prize is established for the scientist who can solve the problem, and the competition is fierce. Collins is heading home one night when he hears a woman’s screams coming from a nearby house.

Without thinking, he breaks into the house and rescues the woman and her little girl. When he learns their lives are in danger, he takes them to his home to keep them safe. The woman is terrified but refuses to tell Collins why.

It’s only after a terrible accident at a demonstration of one scientist’s plan to stop the stink that Collins and Dickens begin to comprehend the truth behind the byzantine story.

Cleverly plotted, deftly written, with vivid characters, rich period ambience, and gentle humor, Harrison’s latest is sure to please fans of historical mysteries.

The Gaslight Mysteries

Spring of Hope The Gaslight Mysteries

Spring of Hope – Kirkus Reviews

A period mystery bolstered by an exciting mix of imagination and historical truth

Another case for those eminent Victorian sleuths Wilkie Collins and Charles Dickens, last seen in Summer of Secrets (2021).

Spring 1859 finds a group of engineers striving to solve the problems of the previous summer, when the River Thames was so overwhelmed with effluent from London that thousands died of cholera and Members of Parliament had to hold their noses as they met.

The queen is offering a cash prize and knighthood to the person who can solve the problem, and Dickens, who’s befriended young engineer Joseph Bazalgette, is eager to help. Collins creates his own mystery when a woman’s fearful screams move him to rescue her and her child from a locked house.

He’s delighted when Caroline, an excellent cook, and her pretty and intelligent daughter, now called Carrie, move into his home, and he soon starts spoiling Carrie, even taking her with him on expeditions to view the engineers’ varied plans to solve the sewage problem.

When he hosts a dinner party for men interested in the problem, Caroline, still terrified of her mysterious former captor, overhears a voice that sends her into a frenzy of fear.

A shocking, seemingly accidental death during a demonstration at Bazalgette’s workshop sends Collins and Dickens on a hunt for a killer even though Collins secretly fears that Carrie may be involved.

A period mystery bolstered by an exciting mix of imagination and historical truth.

Spring of Hope The Gaslight Mysteries

Spring of Hope starred review by Publishers’ Weekly

Victorian whodunits don’t get much better than this.

The prologue of Harrison’s superior fourth Gaslight mystery teaming novelists Wilkie Collins and Charles Dickens (after 2021’s Summer of Secrets), a melancholy letter written by Collins on his deathbed in 1889, sets the stage for flashbacks to 1859.

In the wake of the Great Stink of 1858, during which an overwhelmed London sewer system combined with a heat wave to create a persistent foul odour in the metropolis, civil engineer Joseph Bazalgette, a friend of Dickens, is tasked with addressing the problem.

But murder interferes, as Collins relates in his letter. During an exhibition of Bazalgette’s proposed solution at a gathering attended by notables who include MP Benjamin Disraeli, a man, unidentified in the prologue, is killed in an explosion that sends metal fragments flying.

Collins and Dickens, present at the gathering, come to believe the death was no accident and partner up to seek a murderer.

Amid clever plot twists, Harrison maintains suspense as the action builds up to the fatal explosion, leaving readers in suspense as to who is killed and why.

Collins and Dickens subsequently investigate.

Victorian whodunits don’t get much better than this.

The Reverend Mother is delighted with her new entrant to the convent. Young Sister Gertrude is well-educated, has worked for an accountant and has an appealing sense of humour. But one autumn morning, Sister Gertrude is found dead inside a small wooden shed, just beside the river. Surely a young nun could not die from alcohol poisoning?

But when the Reverend Mother delves more deeply into Sister Gertrude’s background, she finds some puzzling anomalies. Why did the young nun not delay her entry to the convent until after her sister’s wedding? Is it a coincidence that her father died of a similar illness not long before? And could there be a link between Sister Gertrude’s death and the gunpowder explosion on Spike Island? The Reverend Mother must find the answers to these questions if she is to safeguard her community from suspicions of murder.
