The Bookshop Detectives are on the case! In this rollicking new adventure, Garth and Eloise (and Stevie) must sniff out a prolific poisoner ahead of a vital fundraising event, the Battle of the Book Clubs. But time is running out and people are dropping like flies - and the attempted murders seem to be circling closer to the people and places they care about... Could Pinter, the infamous serial killer from Eloise's past, somehow be involved? And when anyone could be a suspect, how can Gareth and Eloise keep their customers, their small town and their beloved bookshop safe?
