2 Sisters Detective Agency

by Candice Fox

2021

Attorney Rhonda Bird returns to Los Angeles to settle her estranged father’s estate and discovers he’s left her both a scruffy private detective agency and a teenage half-sister. Their first case—a young man claiming abduction by a thrill-seeking rich-kid clique—throws the mismatched sisters into deadly trouble.

Series background & context

The 2 Sisters Detective Agency novels, co-written with James Patterson, introduce Rhonda Bird, a sharp-tongued Los Angeles defence lawyer who would rather forget her past than revisit it. When her estranged father dies, she flies home expecting to sign some paperwork and leave again. Instead she discovers two surprises: he’d given up accounting to run a scruffy private detective agency, and he’d secretly fathered a teenage daughter named Baby.

Rhonda and Baby could hardly be more different. Rhonda is organised, guarded and allergic to chaos; Baby is impulsive, social-media savvy and determined to be taken seriously. Circumstances force them into partnership as they decide what to do with the failing agency, and almost before they’ve unpacked the office they’re pulled into their first major case.

In 2 Sisters Detective Agency, a nervous young man walks in claiming he was abducted and terrorised by a clique of rich thrill seekers who treat crime as a sport. As the Bird sisters dig deeper, they stumble into a world of entitled twenty-somethings, violent pranks and an ex-assassin who may be hunting the same targets for his own reasons. The investigation tests Rhonda’s courtroom instincts and Baby’s street smarts, and both sisters have to decide how far they’re willing to bend the rules to protect people who’ve been ignored by the system.

2 Sisters Murder Investigations sees the duo take on a loner whose glamorous wife has gone missing. The media, the police and even some of the couple’s friends are quick to assume he killed her, and hiring the Birds makes him look either very brave or very foolish. As Rhonda and Baby sift through conflicting stories, hidden affairs and a tangle of online personas, they have to work out whether they’re defending an innocent misfit or helping a murderer walk free.

Across the series, the heart of the books is the relationship between the sisters. They bicker constantly, clash over tactics and life choices, and yet keep showing up for each other when it counts. Their banter adds humour to plots that otherwise deal with kidnapping, corruption and cold-blooded violence.

Set against a fast-moving LA backdrop of freeways, diners and backstreet clubs, the 2 Sisters stories offer a different flavour of Candice Fox crime: still twisty and dangerous, but with more gallows humour and a strong thread of found family running through every case.
