The town is celebrating its first literary festival, and The No. 2 Feline Detective Agency has been hired to oversee security.

As the duo turn their attention to investigating the death of Downton Tabby, will there be an author left standing? Will Meridian Hambone sell out of her ‘Littertray' t-shirts? And will there be enough crime teas to go around?
