'The Dog Sitter Detective Plays Dead' by Antony Johnston.
⭐⭐⭐⭐⭐ I'm a big fan of this series and this book did not disappoint. It had murder, drama and a determined little terrier called Lily (who in my opinion breaks the case wide open). I didn't guess who the murderer was till the very end.
If you're a fan of murder mysteries and cozy crime then give this series a read.

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.
