I’m counting down the days to Christmas this December by sharing a different festive whodunnit on the podcast’s social media every day. Follow @ShedunnitShow on Twitter, Instagram and Facebook to see the books! 

I created this list of 25 prompts and I’ll be choosing a story that fits each one. If you take part yourself and post your own festive murder mysteries, use #ShedunnitAdvent to share with the podcast’s community. 

Shedunnit is supporting independent bookshops this Christmas via bookshop.org (read more about how they share profits here). There will be UK and US links to purchase each books there, through which the podcast receives a small commission for referring you, so you can support the book trade and the show at the same time.
