Someone is keeping a Deadvent Calendar. A series of bizarre murders, one for every day of December, with only one thing linking them: all the victims hated Christmas.

Hard to believe, especially for the police, who won't listen to the men who think they have uncovered it, Albert Williams and his friend Shilo Coombes. This can only mean that it's going to be up to them to stop it.

But will Shilo's crazy obsession with Sherlock Holmes be a help or a hindrance? And are they ready for the weird plot they uncover as they open the doors on this Deadvent Calendar?

Deadvent Calendar is a darkly comic murder mystery of fiendish criminal genius, unhinged detectives and one deadly, madcap Christmas.
