The 2 Sisters Detective Agency Mystery series is another collaboration between Candice Fox and James Patterson. The series follows two sisters who inherit a detective agency and must learn to work together despite their very different personalities and backgrounds.
Starting with 2 Sisters Detective Agency (2021), the series has grown to three books. The dynamic between the mismatched siblings gives the crime stories a lighter, more comedic tone compared to Fox’s darker solo work.
