A Swarm of Butterflies
When Finchmere's first summer fete turns fatal, Nell has more than just a killer to net...
Since their YouTube channel, Following Finchmere, has taken flight, showcasing Dr Nell Ward's sustainability transformation at her family's Finchmere estate, it's her partner and colleague, Rav, who's become the star.
Amongst Rav's fan mail and gifts, Nell makes the chilling discovery that one person's obsession with him has metamorphosed into a deadly threat.
Just as Finchmere flings open its gates to welcome swarms of visitors to their idyllic summer fete - celebrating rewilding, artisan produce and local crafts - Nell realises the disguised peril has already wormed its way into the heart of Finchmere itself, and the path of destruction soon leads to murder.
DI James Clark's and Nell's powers of observation are put to the test to detect the camouflaged predator. With everyone as a suspect, who can Nell really trust when those she loves are in danger?
A Swarm of Butterflies is the sixth book in the Dr Nell Ward series. Perfect for fans of Richard Osman, Robert Thorogood and Janice Hallett!

Sarah Yarwood-Lovett
In the quiet folds of the English countryside, where hedgerows hide secrets and shadows stir beneath the underbrush, Sarah Yarwood-Lovett has carved out an unexpected space for crime. Not with flashing lights or high-speed chases, but with the rustle of leaves, the flight of a crow, and the knowing eye of an ecologist who’s spent years decoding nature’s quiet language.
Before she wrote a single line of fiction, Sarah spent over sixteen years as a wildlife specialist, tracking nocturnal mammals, studying animal behavior, and collecting data that would later shape her fictional worlds. That life—spent crouched in woodlands and poring over soil samples—didn’t just teach her patience; it trained her to notice what others might miss. It's this attentiveness that makes her mystery novels sing with authenticity. Her debut, A Murder of Crows, introduced readers to Dr. Nell Ward, a fellow ecologist who can spot a lie as easily as a deer trail. The book quickly soared to Kindle’s Top 5, earning acclaim for its smart, environmentally grounded twist on the classic whodunit.
