Murder mysteries... with dogs!

Guinevere ‘Gwinny’ Tuffel is a retired actress who takes up dog-sitting to make ends meet. But despite her age and outward appearance, Gwinny is a sharp-minded puzzle-solver, and has a habit of stumbling across curious murders which nobody else can solve.

Each book in the series features a different breed, making a fun, light read for lovers of both dogs and mysteries everywhere.

(PS Nothing bad happens to the dogs)

The Dog Sitter Detective

Winner of the Barker Book Award for fiction

Retired actress Guinevere ‘Gwinny’ Tuffel is finding life hard after inheriting her late father’s run-down home and discovering she’s broke. But Gwinny’s delighted to be at her best friend Tina’s country house, for Tina’s wedding to a handsome Italian business magnate... until the husband-to-be is found dead in the library and Tina is accused of the murder.

Convinced of her friend’s innocence, Gwinny must piece together the truth and uncover the real killer from a pool of larger-than-life suspects, who all have something to hide... while also looking after Tina’s expensive saluki dogs!


“A fun, witty page-turner. If Dawn French doesn’t play Gwinny in the TV series, there is no justice in the world!”
Ian Moore

“Brilliantly, compellingly, entertainingly written”

The Dog Sitter Detective
Takes the Lead

Gwinny Tuffel is preparing for her first acting role in a decade in the West End, but she is still dog-sitting on the side to keep the wolf from the door. So, when ageing rock star Crash Double needs help with his Border Collie, she jumps at the chance. After all, looking after the charming Ace on Crash’s Little Venice houseboat shouldn’t be an onerous task. But that’s before the singer’s dead body surfaces during the annual Canal Carnival festivities.

While the police dismiss the death as an accident, Gwinny suspects murder most foul. With a medley of suspects and some far-fetched motives to make heads or tails of, it is up to Gwinny, with Ace’s on the ground knowledge, to make sure the killer faces the music!


“The Dog Sitter Detective Takes the Lead is a dog-lover’s treat, and Gwinny is a delight”
SJ Bennett

“This book is a ton of fun, and I’d wager it’ll even convert cat people into dog lovers. A smashing modern cosy crime novel”
Alice Bell
