Meet Gwinny, an unlikely bloodhound, and her four-legged friends determined to dig up the truth. Penniless Gwinny Tuffel is delighted to attend her good friend Tina's upmarket wedding. But when the big day ends with a dead body and not a happily-ever-after, Gwinny is left with a situation as crooked as a dog's hind leg. When her friend is accused of murder, Gwinny takes it upon herself to sniff out the true culprit. With a collection of larger-than-life suspects and two pedigree salukis in tow, she is set to have a ruff time of it. (Don’t worry, nothing bad happens to the dogs!)

Gwinny Tuffel is preparing for her first acting role in a decade in the West End, but she is 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.

Gwinny Tuffel is on location in the misty Yorkshire Dales filming a small part in Draculania, a genderswapped remake of Bram Stoker’s classic tale, when life begins to imitate art a little too closely. One of the cast members is found dead inside a locked trailer, with a stake through their heart. With a prima donna in the starring role, filming is already facing delays, while Gwinny is being run ragged by Lily, the Jack Russell terrier she’s looking after for a friend in hospital. Against the backdrop of Hendale Hall with its own vampire legend, a flesh-and-blood killer has struck. Will Gwinny be able to find the murderer before the production or any further victims are cut?

It's almost Christmas, and Gwinny Tuffel's thoughts are on what she'll buy for DCI Birch (retired) and whether she can adopt another furry friend. But sorting through her late father's papers leads her into his mysterious past, pointing to an enigmatic liaison now living in a Somerset commune. Gwinny and Birch find themselves unexpectedly snowed in with a group of retired spies, along with an energetic Cocker Spaniel, and embroiled in a murder case. Will they uncover the culprit and escape in time for Christmas?
