The North Shore Mystery

In Short

Set in late nineteenth-century Sydney and its surrounding districts, this narrative centers on the mysterious death of Alexander "Newmarket" Booth and the unjust arrest of his wife, Bertha. As the investigation stumbles, the plot expands into horse racing, bookmaking, and calculated villainy, driven by figures operating in both high and low society. A blend of colonial melodrama and early Australian detective fiction, the book explores how ambition and avarice corrupt human character. Its enduring appeal rests on its vivid historical setting, eccentric cast, and detailed portrait of Sydney’s urban landscape, from harbour ferries to racecourses.

The Story

The quiet routine of Mrs. Delfosse’s Lavender Bay boarding-house is shattered when Alexander Booth, a well-known sportsman writing under the pen name "Newmarket," is found stabbed to death in his second-floor bedroom. His wife, Bertha, becomes the immediate focus of suspicion. Overwhelmed by distress and public scrutiny, Bertha wanders to Blue’s Point and leaps into the harbour, only to be rescued by Police-Constable Hobbs. Her apparent attempt to end her life leads directly to her arrest and commitment for trial.

As the legal system closes in on Bertha, the story turns to two young men seeking their fortunes in Sydney: Alec and Huey. Struggling to secure conventional employment, they fall under the influence of Soft Sam, a shrewd operator who introduces them to the turf. Soft Sam guides them into bookmaking and convinces them to purchase a unruly, high-mettled mare named Bertha. They prepare the horse for the prestigious Sydney Cup, navigating a world filled with fixed matches, cunning handicappers, and corrupt rivals.

Concurrently, Hubert Gosper, a ambitious young man whose lank appearance belies a ruthless nature, becomes obsessively fixated on Bertha Summerhayes. Motivated by greed and romantic obsession, Gosper operates behind the scenes to eliminate anyone in his path. He abducts Bertha using chloroform and later attempts to drown Alec Booth off the quay by trapping his head in a bag and shoving him into the harbour. Alec narrowly survives by clinging to the piling structures beneath the wharf.

While Bertha sits in Darlinghurst Gaol receiving absurd marriage proposals from a sensationalized public, Constable Hobbs continues his investigation. Soft Sam inspects the crime scene at Lavender Bay and detects subtle physical clues at the bedroom window. Hobbs re-examines the sashes and discovers small cuts beneath the catch, realizing the killer bypassed the lock using a blade and loop of wire. This physical evidence, combined with the exposure of Gosper’s extensive schemes, clears Bertha of all charges and reveals Gosper as the true architect of the crime. Following her acquittal, Bertha rewards Constable Hobbs with funds to buy a home, and eventually marries her long-time friend and mentor, Professor Norris, embarking with him on a journey to Paris.

In Its Voice

"The usual quiet of North Shore was this morning rudely dispelled by the alarming rumour that a crime of an unusual kind had been committed in the house of Mrs. Delfosse, Lavender Bay."

The crime immediately grips the local community, setting off endless theories among the populace.

"There is nothing in it that a baby can’t learn in five minutes. You back the field against the public all the time, and the public all finish by losing their money; you always finish by getting it."

Soft Sam dryly explains the ruthless logic of the bookmaking trade to his green protege.

"You cannot rob your brother of silver without at the same time robbing your own mind of gold."

Professor Norris reflects on the moral degradation that ultimately destroys those consumed by greed.
