The Dog Sitter Detective Plays Dead: The tail-wagging cosy crime series

Gwinny is at a stately home in the Yorkshire Dales, filming a small part in a gender-swapped remake of Dracula while looking after the dog of an elderly friend who lives nearby.
During filming, an actor is found dead inside a locked trailer - with a stake through their heart! The film's star, an obnoxious big-shot Hollywood actress who once played a cop on TV, decides she will solve the crime. But Gwinny isn't impressed, and they clash as both women mount rival investigations.
