Book 1

In a London slowly recovering from the ravages of World War II, two very different women join forces to launch a business venture in the heart of Mayfair - The Right Sort Marriage Bureau. Miss Iris Sparks, avuncular and unmarried, and Mrs. Gwendolyn Bainbridge, practical and widowed with a young son, are determined to achieve some independence and do some good in a rapidly changing world.

But the promising start to their marriage bureau is threatened when their newest client, Tillie La Salle, is found murdered and the man arrested for the crime is one Dickie Trower, the prospective husband they matched her with. While the police are convinced they have their man, Miss Sparks and Mrs. Bainbridge are not. To clear Trower’s name - and to rescue their fledging operation’s reputation - Sparks and Bainbridge decide to investigate on their own, using the skills and contacts they’ve each acquired through life and their individual adventures during the recent war.

In this charming, compelling debut, Allison Montclair blends meticulous research with two brilliantly imagined main characters into the first in a wonderful new series.

A Royal Affair

by Allison Montclair

Published 1 July 2020
In London 1946, The Right Sort Marriage Bureau is just beginning to take off and the proprietors, Miss Iris Sparks and Mrs. Gwendolyn Bainbridge, are in need of a bigger office and a secretary to handle the growing demand. Unfortunately, they don't yet have the necessary means. So when a woman arrives - a cousin of Gwen's - with an interesting and quite remunerative proposition, they two of them are all ears.

The cousin, one Lady Matheson, works for the Queen in 'some capacity' and is in need of some discreet investigation. It seems that the Princess Elizabeth has developed feelings for a dashing Greek prince and a blackmail note has arrived, alluding to some potentially damaging information about said prince. Wanting to keep this out of the palace gossip circles, but also needing to find out what skeletons might lurk in the prince's closet, the palace has quietly turned to Gwen and Iris. Without causing a stir, the two of them must now find out what secrets lurk in the prince's past, before his engagement to the future Queen of England is announced. And there's more at stake than the future of the Empire - there is their potential new office that lies in the balance.

Book 3

A Rogue's Company

by Allison Montclair

Published 8 June 2021
In London, 1946, the Right Sort Marriage Bureau is getting on its feet and expanding. Miss Iris Sparks and Mrs. Gwendolyn Bainbridge are making a go of it. That is until Lord Bainbridge-the widowed Gwen's father-in-law and legal guardian-returns from a business trip to Africa and threatens to undo everything important to her, even sending her six-year-old son away to a boarding school.

But there's more going on than that. A new client shows up at the agency, one whom Sparks and Bainbridge begin to suspect really has a secret agenda, somehow involving the Bainbridge family. A murder and a subsequent kidnapping sends Sparks to seek help from a dangerous quarter-and now their very survival is at stake.

Book 5

The Lady from Burma

by Allison Montclair

Published 25 July 2023
In Allison Montclair's The Lady from Burma, murder once again stalks the proprietors of The Right Sort Marriage Bureau in the surprisingly dangerous landscape of post-World War II London.

In the immediate post-war days of London, two unlikely partners have undertaken an even more unlikely, if necessary, business venture - The Right Sort Marriage Bureau. The two partners are Miss Iris Sparks, a woman with a dangerous - and never discussed - past in British intelligence and Mrs. Gwendolyn Bainbridge, a war widow with a young son entangled in a complicated aristocratic family. Mostly their clients are people trying to start (or restart) their lives in this much-changed world, but their new client is something different. A happily married woman has come to them to find a new wife for her husband. Dying of cancer, she wants the two to make sure her entomologist, academic husband finds someone new once she passes.

Shortly thereafter, she's found dead in Epping Forest, in what appears to be a suicide. But that doesn't make sense to either Sparks or Bainbridge. At the same time, Bainbridge is attempting to regain legal control of her life, opposed by the conservator who has been managing her assets - perhaps not always in her best interest. When that conservator is found dead, Bainbridge herself is one of the prime suspects. Attempting to make sense of two deaths at once, to protect themselves and their clients, the redoubtable owners of the Right Sort Marriage Bureau are once again on the case.
