Murder at Mallowan Hall

by Colleen Cambridge

Published 26 October 2021
The first in an exciting new historical mystery series set in the home of Agatha Christie!

Colleen Cambridge's charming and inventive new historical series introduces an unforgettable heroine in Phyllida Bright, fictional housekeeper for none other than famed mystery novelist Agatha Christie. When a dead body is found during a house party at the home of Agatha Christie and her husband Max Mallowan, it's up to famous author's head of household, Phyllida Bright, to investigate...

Tucked away among Devon's rolling green hills, Mallowan Hall combines the best of English tradition with the modern conveniences of 1930. Housekeeper Phyllida Bright, as efficient as she is personable, manages the large household with an iron fist in her very elegant glove. In one respect, however, Mallowan Hall stands far apart from other picturesque country houses...

The manor is home to archaeologist Max Mallowan and his famous wife, Agatha Christie. Phyllida is both loyal to and protective of the crime writer, who is as much friend as employer. An aficionado of detective fiction, Phyllida has yet to find a gentleman in real life half as fascinating as Mrs. Agatha's Belgian hero, Hercule Poirot. But though accustomed to murder and its methods as frequent topics of conversation, Phyllida is unprepared for the sight of a very real, very dead body on the library floor...

A former Army nurse, Phyllida reacts with practical common sense--and a great deal of curiosity. It soon becomes clear that the victim arrived at Mallowan Hall under false pretenses during a weekend party. Now, Phyllida not only has a houseful of demanding guests on her hands--along with a distracted, anxious staff--but hordes of reporters camping outside. When another dead body is discovered--this time, one of her housemaids--Phyllida decides to follow in M. Poirot's footsteps to determine which of the Mallowans' guests is the killer. With help from the village's handsome physician, Dr. Bhatt, Mr. Dobble, the butler, along with other household staff, Phyllida assembles the clues. Yet, she is all too aware that the killer must still be close at hand and poised to strike again. And only Phyllida's wits will prevent her own story from coming to an abrupt end...

A Trace of Poison

by Colleen Cambridge

Published 25 October 2022
“Balances Downton Abbey–style period charm with a tight plot that twists and turns right until the end… a plot that would satisfy Poirot.” – Library Journal

“Dame Agatha would be proud.” – Publishers Weekly

In this captivating English murder mystery from an acclaimed author, Agatha Christie’s housekeeper must uncover the killer amongst a throng of crime writers.


In England’s stately manor houses, murder is not generally a topic for polite conversation. Mallowan Hall, home to Agatha Christie and her husband, Max, is the exception. And housekeeper Phyllida Bright delights in discussing gory plot details with her friend and employer . . .

The neighboring village of Listleigh has also become a hub of grisly goings-on, thanks to a Murder Fête organized to benefit a local orphanage. Members of The Detection Club—a group of celebrated authors such as G.K. Chesterton, Dorothy L. Sayers, and Agatha herself—will congregate for charitable events, including a writing contest for aspiring authors. The winner gets an international publishing contract, and entrants have gathered for a cocktail party—managed by the inimitable Phyllida—when murder strikes too close even for her comfort.

It seems the victim imbibed a poisoned cocktail intended for Alastair Whittlesby, president of the local writers’ club. The insufferable Whittlesby is thought to be a shoo-in for the prize, and ambition is certainly a worthy motive. But narrowing down these suspects could leave even Phyllida’s favorite fictional detective, M. Poirot, twirling his mustache in frustration.

It’s a mystery too intriguing for Phyllida to resist, but one fraught with duplicity and danger, for every guest is an expert in murder—and how to get away with it . . .

Murder by Invitation Only

by Colleen Cambridge

Published 26 September 2023
In this engaging historical mystery, Agatha Christie’s ever-capable housekeeper, Phyllida Bright, not only keeps the celebrated author’s English country home in tip-top shape, she excels as an amateur sleuth. But when a murder-themed game goes awry, can she outfox the guilty party?

“A murder will occur tonight at Beecham House . . .” Who could resist such a compelling invitation? Of course, the murder in question purports to be a party game, and Phyllida looks forward to using some of the deductive skills she has acquired thanks to her employer, Mrs. Agatha, who is unable to attend in person.

The hosts, Mr. and Mrs. Wokesley, are new to the area, and Phyllida gladly offers their own overwhelmed housekeeper some guidance while events get underway. Family friends have been enlisted to play the suspects, and Mr. Wokesley excels in his role of dead body. Unfortunately, when the game’s solution is about to be unveiled, the participants discover that life has imitated art. Mr. Wokesley really is dead!

In the absence of Inspector Cork, Phyllida takes temporary charge of the investigation, guiding the local constable through interviews with the Murder Game actors. At first, there seems no motive to want Mr. Wokesley dead . . . but then Phyllida begins to connect each of the suspects with the roles they played and the motives assigned to them. It soon becomes clear that everyone had a reason to murder their host—both in the game and in real life. Before long, Phyllida is embroiled in a fiendishly puzzling case, with a killer who refuses to play by the rules . . .

Murder Takes the Stage

by Colleen Cambridge

Published 22 October 2024
In this delightful historical mystery, Phyllida Bright—amateur sleuth and Agatha Christie’s esteemed housekeeper—discovers a killer stalking the stages of London’s illustrious theaters.

Housekeeper Phyllida Bright is quite in her element at Mallowan Hall, the charming English manor that she keeps in tip-top shape. By contrast, the bustling metropolis of London, where her famed employer Agatha Christie has temporarily relocated, leaves Phyllida a bit out of her depth. Not only must she grapple with a limited staff, but Phyllida also has to rein in a temperamental French cook who has the looks of Hercule Poirot, but none of the charm.

When a man named Archibald Allston is found dead in an armchair onstage at the Adelphi Theater, first impressions are that he died of natural causes. But the very next day, the unlucky actor playing Benvolio at the Belmont Theater is found with his head bashed in. And when a third victim turns up, this time with double-C initials, the fatal pattern is impossible to ignore.

With panic erupting among theater folk—a superstitious bunch at the best of times—Phyllida steps up to help with the investigation. The murderer’s MO may be easy to read, but can Phyllida uncover the killer’s identity before the final curtain falls on another victim?
