Lady Katherine wants to be a detective, not a matchmaker. But if taking a job will help her catch a killer and earn her independence, she will make one more match.

Lady Katherine must juggle advising her client on how not to land a Duke while she investigates a string of baffling burglaries in Bath.

When a tragic accident turns out to be murder, Lady Katherine finds herself embroiled in an investigation tainted by lies and deception.

Lady Katherine juggles Christmas festivities, a perplexing cold case and a wager with the annoying Captain Wayland that will prove once and for all which of them is the better detective.

It’s the Christmas season in London, but the holiday festivities don’t deter Lady Katherine from investigating a death that happened months earlier. Since the victim was a maid, investigative resources were sparse, and the police hastily wrote it off as a random killing. But Lady Katherine and her friends believe it was nothing short of premeditated murder, and they vow to seek justice.

With her Bow Street Runner friend Lyle acting as a neutral party, Katherine teams up with her friend Prudence Burwick, her maid, Harriett, and of course her pug, Emma. Wayland has the aid of Pru’s fiancé, Lord Annandale, and his valet McTavish.

The two teams race against each other in a hunt for clues that takes them through the servants’ quarters, stables, and seedy underbelly of London in search of a dangerous killer who thinks they got away with murder.

Will the best men... or women… win?

Lady Katherine’s happiness at her newfound independence is shattered by the death of her elderly neighbor, Doctor Gammon. The doctor had become a trusted friend and had confided in Katherine that something about a former patient’s case had been bothering him.

Was it any coincidence he’d ended up dead the very next day?

Katherine doesn’t think so, especially when she discovers the case files he’d been scrutinizing the night before his death seem to have disappeared.

But with her maid Harriett focusing on the vile concoctions she makes for supper, her detecting partner Pru too wrapped up in her fiancee and upcoming wedding plans and her Bow Street runner friend Lyle embroiled in the official investigation, Lady Katherine has only one friend who seems interested in investigating - Captain Wayland.

Her father would have a fit if he knew Katherine was conferring on a case with the handsome Captain, but Lady Katherine will stop at nothing to bring her friend’s killer to justice.

When the case takes a disturbing turn, even Wayland can’t help, and Lady Katherine has only her wits - and her pug Emma - to relay on in order to prevent becoming the next victim.
