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)

“A country house, a body in the library, a cast of dodgy wedding guests, and a prickly, dog-loving sleuth... Simply delightful!”

The Dog Sitter Detective


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 tail-wagging, wet-nose delight of a book! A clever whodunit with plenty of clues, red herrings and misdirection”
Fiona Veitch Smith

Death in Little Venice


Gwinny Tuffel, the dog sitter, stays at an ageing rock singer’s Little Venice houseboat to look after his border collie while he’s on tour. But during the annual Canal Carnival, the singer’s dead body is discovered, having never made it out of London.

The police dismiss it as an accident, but Gwinny suspects murder most foul. It is up to her to solve this curious crime...


“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
