Twelve-year-old Myrtle Hardcastle has a passion for justice and a Highly Unconventional obsession with criminal science.

Armed with her father’s law books and her mum’s microscope, Myrtle studies toxicology, keeps abreast of the latest developments in crime scene analysis, and Observes her neighbours in the quiet village of Swinburne, England.

When her next-door neighbour, a wealthy spinster and eccentric breeder of rare flowers, dies under Mysterious Circumstances, Myrtle seizes her chance. With her unflappable governess, Miss Ada Judson, by her side, Myrtle takes it upon herself to prove Miss Wodehouse was murdered and find the killer, even if nobody else believes he – not even her father, the town prosecutor.

With sparkling wit and a tight, twisty plot, Premeditated Myrtle, the first in a series from an award-winning author, introduces a brilliant young investigator ready to take on hard cases and maddening Victorian rules for Young Ladies of Quality in order to earn her place among the most daring and acclaimed amateur detectives of her time or any other.
